  1. magyarítás

    Ja, bocsi, én úgy értettem, hogy a páncél szó nem tetszik neked, nem gondoltam, hogy az autó és gépkocsi szavak között vívódsz.
  2. magyarítás

    A páncélozott gépkocsi azért nem jó, mert a fontos politikai személyeket szállító gépkocsik is páncélozott autók, de mégsem páncélgépkocsik. Ez a magyar nyelv szépsége. A páncélozott azt jelenti, hogy meg van erősítve bizonyos helyeken olyan elemekkel amelyek bizonyos fokú védettséget biztosítanak (pl. golyóálló üveg, ajtó, stb.). A páncélgépkocsi pedig egy olyan - többnyire négykerekű - járművet jelent, ami teljes egészéből katonai páncéllemezekből épült fel.
  3. magyarítás

    A páncélgépkocsit, a páncélkocsit és a páncélautót is mind használják a szakirodalomban. Legtöbbször a páncélgépkocsival lehet találkozni, de igazából mind megfelelő. Nekem mondjuk a páncélautóról mindig ez jut eszembe:
  4. Angling your tank helps at mid-to-long range fights. But when you're in a close range, head-to-head fight, angling won't always help because at this distance the enemy's gun is the strongest in terms of armor penetration. The T-28 doesn't have strong enough armor at that distance and as you saw it has more weak points. But for example a T-34 is good in such fights too, even angled.
  5. Part 2: Hungarian tank shells Since she was a part of Austria-Hungary factories which produced explosives - especially TNT - were built in the territories of Hungary which stayed in the region even after the Treaty of Trianon, not to mention that after WW1 a huge amount of explosives were stocked too. During WW1 all the industries which manufactured explosives were considered to be defense plants therefore the art of explosive production didn't get out to the civilian life, after the Great War the Treaty of Trianon forbid Hungary to have medium or heavy artillery, AA artillery and an Air Force so it's right to assume that the Entente kept a close eye on Hungary and forbid the production of any explosives which are stronger than TNT and could be used by the military. Because of this the main explosive of Hungary at the beginning of WW2 was still the TNT or the Amatol (mixture of TNT and ammonium nitrate, Hungary used a 60% TNT - 40% AN mixture) but some artillery shells and mines used nitrostarch too. It's not clear when but before WW2 Hungary was able to produce pentaerythritol tetranitrate (PETN), probably after the Entente Committee left Hungary in 1927, but the amount of produced PETN was not enough for the whole Hungarian Armed Forces, still some armor-piercing high-explosive shells were filled with this explosive at the beginning of WW2. We also have datas that after the German occupation of Hungary in March 1944, the Hungarian Nitrokémia Zrt. produced PETN and tetryl after the German Meissner works' patent. From August 1942 Hungary started to use pentolite 50/50 (known as NPT in Hungary during WW2) in armor-piercing high-explosive shells. Originally the Hungarian Ministry of Defense wanted an explosive which could be used in modern anti-tank mines since the ones Hungary used at that time were filled with nitrostarch and were not effective enough. They wanted an explosive which was 30-40% more effective than TNT but at that time they didn't know anything better than PETN or RDX, but since the production of RDX in Hungary was out of the question - because it was too complicated - they started to make experiments with PETN and other explosives. That's when they found out about the pentolite 50/50 and realized that it could be used not just in mines but also in shaped charges and armor-piercing high-explosive shells too. Of course it was not without danger: on March 26, 1942 a fatal accident happened at the Nitrokémia Zrt. where the experiments were carried out, one worker died and 7 more were injured when they tried to fill land mines and aerial bombs. It should be mentioned too that the lack of minerals also affected the tank shell production. At the beginning of the war Hungary had enough materials to make shells from CrNi material, but from August 1941 the tank shells were made out of Manganese-Carbon Steel material. List of tank shells ARMOR-PIERCING HIGH-EXPLOSIVE SHELLS 20 mm 36.M páncélgránát - The name means "20 mm 1936 patterned armor-piercing grenade", the word "páncélgránát" comes from the German panzergranade and implies that it's a shell with a bursting charge. The shell had a tracer but didn't have a ballistic cap, its bursting charge was TNT or PETN, later it was pentolite 50/50. This shell was used by the 36.M Csaba armored cars and 38.M Toldi light tanks. 40 mm 36.M páncélgránát - The name means "40 mm 1936 patterned armor-piercing grenade". Equipped with tracer and ballistic cap, its burting charge was TNT or PETN, later pentolite 50/50. This shell was used by the 38/42.M Toldi (a.k.a. Toldi IIa) and 43.M Toldi (a.k.a. Toldi III) light tanks, the 40.M Turán (a.k.a. Turán I) medium tanks and untill 1943 the 36/40.M Nimród SPAAGs. Before 1943 the Nimród SPAAGs were used as tank-hunters AND self-propelled anti-aircraft guns but from that date they were stoped being used as tank-hunters and focused mainly on anti-aircraft role, therefore this shell was not needed anymore for the Nimród. 7.5 cm 42/36.M páncélgránát - The name means "7.5 cm 1936 patterned armor-piercing grenade modified in 1942". This grenade was similar in construction to the 40 mm 36.M. Since it was produced from 1942 the bursting charge of this shell was pentolite 50/50 from the start. It was used by the 41.M Turán (a.k.a. Turán II) medium tanks. 7.5 cm 43.M páncélgránát - The name means "7.5 cm 1943 patterned armor-piercing grenade". It was the shell of the 43.M tank gun which was used by the 43.M Turán (a.k.a. Turán III) tank and 44.M Zrínyi (a.k.a. Zrínyi I) tank-hunter. Since the 43.M tank gun was a licence built tank gun variant of the German 7.5 cm PaK 40 anti-tank gun (and NOT the KwK 40 tank gun) the shell itself was a licence built version of the German Panzergranate 39. HIGH-EXPLOSIVE SHELLS 20 mm 36.M repeszgránát - The name means "20 mm 1936 patterned high-explosive grenade". The shell didn't have a tracer and its bursting charge was TNT. It was used by the 36.M Csaba armored cars and 38.M Toldi light tanks. 40 mm 39.M légvédelmi repeszgránát - The name means "40 mm 1939 patterned anti-aircraft high-explosive grenade". This shell had a self-destroying fuse in it too since it was used against aircrafts. The self-destroying fuse detonated the shell in mid-air if it didn't hit anything and the head fuse didn't blew up the shell. The shell was used by the 36/40.M Nimród SPAGGs. The bursting charge of the shell was TNT, the fuse lasted 11 seconds 40 mm 39.M repeszgránát - The name means "40 mm 1939 patterned high-explosive grenade". It was identical to the anti-aircraft variant but it didn't have a self-destroying fuse since it was used by tank guns and anti-tank guns. Since it was not used by AA artillery and the crew didn't need to follow its trace by eye - since it was use against infantry and soft armored targets in close range - this shell didn't have a tracer and could be filled with around twice as much TNT. This shell was used by the 38/42.M Toldi (a.k.a. Toldi IIa) and 43.M Toldi (a.k.a. Toldi III) light tanks, and the 40.M Turán (a.k.a. Turán I) medium tanks. 7.5 cm 42/38.M repeszgránát - The name means "7.5 cm 1938 patterned high-explosive grenade modified in 1942". The 38.M repeszgránát was originally a 40 mm high-explosive shell for the 40 mm Bofors AA autocannon, produced in Hungary for export to the UK. The 38/42.M was a variant of this shell and was quite similar to the 40 mm 39.M repeszgránát. It didn't have a tracer and was filled with TNT. It was used by the 41.M Turán (a.k.a. Turán II) and 43.M Turán (a.k.a. Turán III) tanks and by the 44.M Zrínyi (a.k.a. Zrínyi I) tank-hunter. 8 cm 14/29.M légvédelmi repeszgránát - The name means "8 cm 1914 patterned anti-aircraft high-explosive grenade modified in 1929". Although it's displayed as a 8 cm shell its true caliber was 76.5 mm. This shell was used by the 5/8.M cannon of the Rába Vr self-propelled anti-aircraft gun. It had a timed fuse so it didn't blew up on impact but it was equipped with a tracer. Its bursting charge was TNT. 10.5 cm 38/33.M repeszgránát - The name means "10.5 cm 1933 patterned high-explosive grenade modified in 1938". This grenade was an artillery shell and as such didn't have a tracer. Most commonly it was filled with TNT or Amatol (60%TNT-40%AN). It was used by the 40/43.M Zrínyi (a.k.a. Zrínyi II) assault howitzer. 15 cm 43.M repeszrakéta - The name means "15 cm 43.M high-explosive warhead". This rocket warhead was the high-explosive warhead of the 43.M rakéta sorozatvető which was a licence built version of the German 15 cm Nebelwerfer 41, the rocket itself was the licence built variant of the 15 cm Wurfgranate 41 Spr. This rocket was used by the experimental Zrínyi I tank-hunter which had 6 rocket launcher tubes. Zápor rakéta - The name means "Downpour warhead". This rocket warhead was the high-explosive warhead of the Hungarian 44.M Buzogányvető. It was filled with around 4 kg TNT. It was used by the experimental Toldi light tank which was armed with a 44.M Buzogányvető rocket launcher. ARMOR-PIERCING SHELLS 40 mm 43.M magvas páncélgránát - The name means "40 mm 1943 patterned steel cored shell". Originally it was developed for the 40 mm Bofors AA autocannon to have an effective shell which could counter hostile armored aircrafts. Because of this the shell had an incendiary powder mix in its head, so in reality it's an armor-piercing incendiary shell. All we know that the powder mix had barium peroxide in it and the ballistic cap of the shell was made out of aluminium, perhaps the two materials reacted with each other on impact. Because it was developed for the Bofors AA autocannon the ballistic characteristics of the shell matched with the 40 mm 39.M anti-aircraft high-explosive shell's and the two were used in mixed clips, therefore the AP shell had a tracer which lasted for 2 seconds. However because its armor-piercing capabilities surpassed the 40 mm 36. armor-piercing high-explosive shell's the 43.M armor-piercing shell was issued to all 40 mm tank guns and anti-tank guns too. Therefore this shell was used by the 38/42.M Toldi (a.k.a. Toldi IIa) and 43.M Toldi (a.k.a. Toldi III) light tanks, the 40.M Turán (a.k.a. Turán I) medium tanks and the 36/40.M Nimród SPAAGs. Hungary also used the German Panzergranate 40, an armour-piercing, composite rigid (APCR) projectile with a sub-calibre tungsten core, but these shells were not manufactured in Hungary, not even as a licence built variant since Hungary didn't have the proper industrial capacities to produce tungsten. The PzGr. 40 shells which Hungary recieved from Germany were used by the 7.5 cm anti-tank guns (also recieved from Germany), and by the 43.M Turán (a.k.a. Turán III) tank and the 44.M Zrínyi (a.k.a. Zrínyi I) tank-hunter. The Hungarian designation of the German shell was 7.5 cm 40.M különleges német páncélgránát, meaning "7.5 cm 1940 patterned special German armor shell". SHAPED CHARGES (HEAT) 40 mm 42.M páncélrobbantó gránát - The name means "40 mm 1942 patterned armor-demolition grenade". It was a Hungarian shaped charge, fin-stabilized shell, used with the 40 mm Bofors AA autocannon or the 40mm 40.M anti-tank gun. It had two variants, the 42.M (left) and the 42/a.M (right). The difference between the two is that the 42/a.M is more wider and because of that the muzzle brake on the 40 mm Bofors AA gun wasn't need to be removed, while in the case of the 42.M it had to be removed otherwise it would not fit. The explosive around the conical liner was TNT while the detonator was pentolite 50/50. This shell was used by the 36/40.M Nimród SPAAGs. 7.5 cm 42.M páncélrobbantó gránát - The name means "7.5 cm 1942 patterned armor-demolition grenade". This shaped charge was a licence built version of a German Hohl-Ladung shell. Its explosive around the conical liner was TNT while the detonator was pentolite 50/50, it had a tracer. It was used by the 41.M Turán (a.k.a. Turán II) and 43.M Turán (a.k.a. Turán III) tanks and by the 44.M Zrínyi (a.k.a. Zrínyi I) tank-hunter. 10.5 cm 42.M páncélrobbantó gránát - The name means "10.5 cm 1942 patterned armor-demolition grenade". A bigger version of the 7.5 cm shaped charge. Its explosive around the conical liner was TNT while the detonator was pentolite 50/50, it was equipped with tracer. This shell was used by the 40/43.M Zrínyi (a.k.a. Zrínyi II) assault howitzer. Buzogány rakéta - The name means "Mace warhead". This rocket warhead was the shaped charge warhead of the Hungarian 44.M Buzogányvető. It had a double bursting charge with 1,75 kg TNT and 2,32 kg pentolite 50/50, the detonator was 0,142 kg PETN or pentolite 50/50. It was used by the experimental Toldi light tank which was armed with a 44.M Buzogányvető rocket launcher.

  6. Now those I'd love to see. If there are enough to do a complete TT, then I'll fully support this idea. But as it is right now I can't agree with it, sorry.
  7. Yes. If something was added which changes the vehicles' behaviour or specification, then I can accept it - as should others too in my opinion - because of the aforementioned resons in the British TT. For example I would love to see the LVT-4/ZiS-2. I'm not saying that a repainted tank is OK. A repainted tanks is still a tank of another nation. But if a TT doesn't have enough vehicles to make a full Tier to unlock the next one I say it's acceptable but only if it's 1 or 2 tanks. If that'd be the case with China I'd say that it's OK too, but in China's case it's not just 1 or 2 vehicles but complete Tiers. Take a look at Japan's GF tree: where do you see repainted tanks? From Tier III. How many? 2 out of 6 in each Tier III-IV. Now take a look on the suggested Italin GF tree: where do repainted tanks appear? At Tier IV (APCs) and they are even modified vehicles. How many do you see? Only 2 in Tier IV, and yes, your point is taken here, almost all of Tier V. Now let's take a look on the Chinese tree: repainted tanks are appearing right from the start and make almost half of the vehicles in each tier up to Tier IV. And we're back again to the point that the Chinese TT is mainly consisting repainted lend-lease tanks and few original vehicles especially at low tier. Now you're saying that Italy - as it is right now - would be a multination nation and would make high tier fight complicated in RB and SM battles because so many players don't pay attention to the paintings. Yes, it'd be more easier for China because it'd always be on Russia's side. However I'd say that if a player can't identify a friendly tank from an enemy tank in RB deserves to be killed in the game because in RB you've got the IFF option and an enemy tank will have a huge red line right above it's turret when seen. And isn't there an algorithm in SB that would make an American high Tier Italian vehicle be placed into an Allied team?
  8. Very intresting article. Thanks for sharing. It also shows how much propaganda can exaggerate things.
  9. You're forgetting some things: At Tier V you don't need to have at least 6 vehicles. From Tier I to Tier IV however you need at least 6 to unlock the next tier. Italy has enough vehicles for that. China on the other hand hardly (based on the suggested TT China has 4 tanks in Tier II and only 2 in Tier III, and the majority of those vehicles are Russian and American tanks) The Sherman II, Sherman Firefly and Achilles are British tanks. They are basically American Shermans and M10 TD but one has a special British ammo and the other two have 17-pounder British guns. Therefore every American tank in the suggested Italian TT with an Italian gun is considered to be Italian. Italy lost WW2 so according to the restrictions of the Treaty of Paris she was not allowed to have her own tanks and planes for quite a while (same with Japan and Germany). Therefore her Air Force and Army was equipped mostly with Allied stuff, that can't be helped. As a matter of fact China hardly has anything original from Tier I to Tier III just Russian and American vehicles so based on your logic the Chinese GF and AF TT are jokes (no offense). You can't do anything with teammates who doesn't pay attention to paintings. Again, I'm not looking down on China and I'm hoping to see original or modified Chinese vehicles in the game someday, but I can't stand this pointles "blind witch hunt to prove that others - especially Italy - don't have more rights than us to have a TT".
  10. Part 1: Hungarian armor plates Since Hungary lacked the necessary minerals for armor plates it relied heavily on imports but with Germany's constant territorial gains it was almost impossible. Since the beginning Germany forced an "economic co-operation" on Hungary which in reality was a one-sided trading contract between the two countries with Hungary constantly fulfilling her part to the max. - she was offten forced to lower her civilian and military needs to the very minimum - while Germany just kept promising an increased the export demands from Hungary often using threats and blackmailing. Also with other European trading partners of Hungary being occupied by Germany did not helped either and since most of the trading lines went through German occupied territories the connection between Germany and Hungary was even stronger. Because Germany didn't fulfill her part of the contracts and constantly kept her exports of minerals to a minimum - also these shipments offten arrived much later than she promised - Hungary was forced to seek for substitute minerals. Expermients for such minerals were successful, however their research was not cheap. At the very beginning Hungary had a lot of minerals stored up. The 38.M Toldi light tanks, 36/40.M Nimród SPAAGs and 39.M Csaba armored cars all had good quality armor plates made from Chromium-Nickel-Molybdenum (Cr 1,0-2,0% - Ni 4,0% - Mo 0,3%). It's important to point out that at that time Hungary was specialised in making 13 mm or thinner armor plates. At the end of the 30s Hungary used CrNi armor plates to test her own armor-piercing shells, those armor plates had a tensile strenght of 100 kg/mm2 (980.665 MPa), but tests of the 8 mm 31.M armor piercing cartridge were also carried out on 10 mm and thinner armor plates which had a tensile strenght of 180-200 kg/mm2 (1765.197-1961.33 MPa). We can assume that the armor plates of the aforementioned fighting vehicles also had armor plates of similar quality. In 1941 however the lack of noble metals became a problem and researches for substitute minerals began. In March 1941 the Stell Forging Mill in Diósgyőr presented one of its enginner's work, the Mester's armor plate. Mester's armor plate used only those minerals which were mined in Hungary with Chromium being the only exception. The Mester's armor plate's composition: C 0,55-0,72% - Mn max. 0,5% - Si max. 0,35% - Cr max. 0,65%. The armor plate had good capability of resistance and the production started in May 1941. The problem with the Mester's armor plate was that only 13 mm and thicker armor plates could be made out of it, the production of thinner armor plates resulted in a huge number of scrap - 40-50% or in some cases even 80%. Because of this armor plates of 13mm or thinner were all made of Chromium and Nickel similar to the armor plates used in the Toldi, Nimród and Csaba vehicles but with less Nickel and completly abandoning the Molybdenum (Cr 1,0-2,0% - Ni 1,0-1,5%). The 40.M Turán tanks used Mester's and Chromium-Nickel armor plates. The drawback of the Mester's armor plates demanded more research. In October 1942 a new armor plate was made; the Ajax armor plate. The Ajax armor plate was good for 13mm and thinner armor plates but the developers managed to make 25-50 mm thick armor plates too which almost equalled in quality with the Mester's armor plate but it still was inferior to the Mester's armor plate in capability of resistance. However the Ajax armor plate used Titanium which was an import mineral. Hungary managed to store Titanium from Switzerland and Belgium before the war but from 1940 the supply of this material was not possible only through Germany. Therefore experiments strated in 1943 to replace the Titanium with Aluminium, a mineral that Hungary had in a huge amount. Another drawback of the Ajax armor plate was that it's heat treatment was more complicated, but it also had an advantage over the Mester's armo plate: it didn't need alignment. The Ajax armor plate's composition: C 0,45-0,55% - Mn 1,0-1,3% - Si max. 0,4% - Cr 0,8-1,0% - Ti max. 0,3%. Since the mass-production of the 41.M Turán tanks started around this time it's highly possible that these vehicles used Mester's armor plates ande Ajax armor plates. From then on 40.M Turán tanks also started to use Ajax armor plates for their thinner armor. Since Toldi tanks were produced until 1942, while Nimród SPAAGs and Csaba armored cars were produced untill 1944 it's highly possible that some of them were fully made out of Ajax armor plates and reduced Nickel containing CrNi armor plates. Also the additional armor plates of prototypes of the 38/42.M Toldi (Toldi IIA) and 43.M Toldi (Told III) were probably all made out of Chromium-Nickel armor plates but the serial vehicles most likely used Ajax armor plates since it was available when mass production started. It's also need to mentioned that at that time the CrNi armor plates produced by Hungary had a Brinell strength of 300 Brinell. Both the Mester's and Ajax armor plates at that time had a common feature; they were brittle. When a 50 mm thick plate was hit by a large caliber gun - 7.5 cm or larger - it didn't provide enough protection and the fragments were very dangerous to the tank crews. To reduce the fragility of both armor plates the Hungarian Institute of Military Technology decided to face-harden the armor plates while keeping the Chromium-Manganese alloy. It's also important to mention that from 1942-43 a lot of armor plates were made in electric arc furnaces. There was a problem in the production of 75 mm thick armor plates for a while since Hungary lacked the industrial capacity for that. For a time a 75 mm armor plate was possible only by placing three 25 mm thick armor plates together. Because of that the first few Zrínyi assault guns had that kind of "sandwiched" armor. However in October 1943 a new 75 mm thick Ajax armor plate was made. This armor plate had an acceptable 78-90 kg/mm2 (764.9187-882.5985 MPa) tensile strength and provided better protection against 7.5 cm caliber guns than the 50 mm thick armor plates. The 75 mm Ajax armor plate's composition: C 0,32-0,40% - Mn 0,9-1,2% - Cr 1-1,7% - Si max. 0,4% - Va max. 0,2% - Ti max. 0,15%. From that time on the Zrínyi assault guns all used this type of Ajax armor for their frontal armor plates. A serial 43.M Turán and 44.M Zrínyi probably would had this type of armor too. For armor plates thicker than 75 mm - 100 and 120mm to be exact - Hungary tried to buy the licence of the German armor plates since - to our current knowledge - she didn't have the proper indutrial capacity to build such thick armor plates. These armor plates were meant to be used for the 44.M Tas project. However Germany probably refused to sell the armor licence - as she did many times before. Also, when Hungary was occupied by Germany in March 1944 the Germans constantly gained more and more influence in the Hungarian war industry and started to forbid any "unnecessary developments" since they wanted to use Hungary's materials for their own sake, therefore a project such as the Tas tank which was a completly new design even for Hungary was considered to be an "unnecessary development" in the eyes of Germany. Even tho the Tas project continued which means that it was either accepted by the Germans - which is hardly imaginable - or that it was kept hidden even from them. Since the Hungarian Ministry of Defence ordered a mild steel prototype and a military-quality steel prototype of the Tas tank it's assumed that the problem of the 100 and 120 mm armor plates were somehow solved, if not the Tas project would be delayed because of the lack of armor plates. This can either mean that the Hungarian engineers managed to develop a not yet known 100-120 mm armor plate or that they welded two armor plates together.

  11. I believe someone asked me for blueprints of the Tas tank (@blockhaj if I remember right). I finally managed to find some digitalized ones at another webpage. These blueprints don't show the whole tank but specific parts of it.

  12. Na, most nagy kémikusok segítségét kérném. A Második Világháború alatt a mérnökeink megalkották a 43.M magvas páncélgránátot. Ezen a képen a jobb szélen látható. A képen látszódik, hogy a lőszerre egy alumínium ballisztikai süveget csavartak. Az acélmag és a ballisztikai süveg között gyújtótöltet van (rózsaszín). Ez a magyar szakirodalom szerint porkeverék, továbbá a bárium-peroxidot is megnevezik. Legjobb tudomásom szerint a bárium-peroxidot mint gyújtókeveréket alumíniumtermit begyújtására is használnak. Lehetséges, hogy lőszerben lévő gyújtótöltet becsapódáskor reakcióba lép az alumínium sapkával és kb. 2400 °C-os lánggal égés jön létre? Mert erről a Haditechnika magazin nem ír. Gyújtótöltetként tuti, hogy lángra lobbantja a célpontot én igazából a várható reakció hevességére vagyok kíváncsi. Hozzáteszem, hogy a gránátot első sorban páncélozott támadó repülőgépek ellen tervezték, csak a sikeres tesztek után javasolták páncéltörő- és harckocsiágyúkban is használni.
  13. Jó kis német Artilleriefährprahm. Ha valakit érdekel, akkor itt egy egészen jó oldal a német haditengerészeti hajókról, persze angolul: http://german-navy.de/kriegsmarine/ships/index.html
  14. Egy picikét azért nevetségesnek találom, hogy a Jumbo Sherman egy teljes BR ponttal van a Tigris alatt, miközben röhögve lepattintja magáról a 88 mm-es páncélgránátot is.
  15. I managed to find some new datas therefore I edited the datas about the explosive fillers in Hungarian shells:
  16. A robbanóanyagokkal kapcsolatos írásom ismét frissítésre került, mert mostanában jutottam hozzá olyan képekhez amik kissé megváltoztatták az eddigi állításaimat. Továbbá a pentritol rövidítésével kapcsolatban is új infók kerültek elő. A Haditechnika magazinban az anyagot TNP-nek rövidítik, ami egyébként a pikrinsav (egy másik robbanóanyag) rövidítése, az archív Magyar Katonai Szemlében pedig egyszer írják csak a rövidítését, amit NPT-nek írnak. Emiatt sem az NPT-t, sem a TNP-t nem töröltem az írásból, de magyarázatot odaírtam. Továbbá szeretnék majd kérni, egy fórum moderátort, hogy majd valamikor törölje ezeket a nem a topichoz kapcsolódó postokat, mert kissé elrondítottuk.
  17.   Although not really a tank, but an IFV, it had this anti-tank variant which could be a Tier IV or Tier V light vehicle for the German branch.   Dimensions 5,56 x 2,54 x 1,85 m (18.2 x 8.3 x 6 fts)   Total weight, battle ready 14.6 tons (32,187 ibs)   Crew 3+5 (Driver, commander, gunner, 5 infantrymen)   Propulsion Rolls-Royce B81 Mk 80F 8-cyl gas. 220 hp (164 KW)   Suspension Independent torsion bars   Speed (road) 58 kph (36 mph)   Range 270 km (168 mi)   Armament Main : Rheinmetall (HS) 20 mm autocannon Sec. coaxial 7.62mm MG3 machine gun. Terc. 106 mm M40A1 recoilless rifle   Armor 30 mm front and sides (1.2 in)   Total production 2176 in 1958-71. http://www.panzerbaer.de/types/bw_spz_lg_hs30-a.htm   The 106 mm recoilless rifle had acces to HEAT, HESH and HE rounds and with the american HEAT round it could penetrate through 400 mm of armor. Furthermore it had the effective range of 1350 m so it won't be an only close-quarters vehicle.
