“no number no upgrade”
it has been like that for a while, gaijin is scared because if they make an educate guess and up the abrams armor the RU main would cry because they cant W and click easily anymore and has to aim for weakspot
That is exactly part of the problem. Gaijin wants distinct numbers but they themselves cannot post the sources or otherwise of changes and adjustments to vehicles already in the game for the USSR and China Nations. I understand changes for balance but when you have certain vehicles underperforming when compared to others you either buff the ones underperforming or you nerf the overperforming ones. Instead they continually buff and add broken things to nations that are already so far from “Historical” that it clearly shows the intent. Meanwhile we have to try and find exact texts listing the procetion of X from X at X distance from X angle. We get to play document Gymnastics because they want the exact specification when they can look at the actual documents available and have been provided in reports and otherwise and see that there is CLEARLY improvements or upgrades over the previous models and go okay so lets increase it by X to keep it fair for a balancing prospective.
Lets be real if the Protection values of A2, A2 Sep (1,2,3) were declassified Gaijin would look at them and go NOPE thats unfair for the game. Meanwhile we get Kontact-5 defeating DM53, 829a2, and l27a1. All rounds that had been developed to perform better against the REDFOR ERA.
You are misunderstanding the point of the Parathensis. Abrams Heavy (DU armored) tank. Heavy = Descriptor = DU armored as the Heavy is being described as the Depleted Uranium Armor. Thus the CBO Report using the EXACT Descriptor of the Armor on the HULL and TURRET. Heavy = DU End of Story
They upgraded the DU armor with the M1A1 HA+, the M1A1 HC uses the same armor as the HA+.
(M1A1 HA) → (M1A1 HA+) → (M1A1 HC) → (M1A2 Block II MBT).
That’s not how deduction works.
Supposedly the HA has first generation DU armor, and the HA+ has second generation (same as the HC).
Heavy Armor = Depleted uranium armor
per NRC not just CBO

Note: This is from 1996 so the hulls getting DU in 1998+ doesn’t impact the text here where it says its only in the turret.

Their margin for reducing the armor is very small, because according to recently discovered TACOM documents, they manufactured 4 In. DU billets for DU equipped tanks, but it is unknown how they used these billets. In the old forum, someone posted a source claiming that depleted uranium encased in steel was located in front of the 4-inch turret backing plates.
How do you guys get all these documents? Also M1A1 HC and M1A1 HA different right?
Google skillz™
Nah, but just learning how google prioritizes searches and how to add specific symbols to the searches to change the results does a lot.
I personally usually start with a reverse image search if it’s something new, sometimes people here on the forum add links at the bottom of their screenshots of the documents.
This topic was brought up and already answered by the developers 3 years ago so some of the documents are linked in the official post: ( Hull Armor of the M1 Abrams ).
Then you can see what the license number is and google that licence number to find related documents.
A great tip is to add " filetype:pdf " at the end of your search because then all results you get will be pdf files.
Another tip is to use the quotation marks " " to highlight words or part of the sentence that HAS to be exactly like that in the result.
This literally just helped me find a declassified technical report on the CATTB, which I had only been able to find through Scribd with its stupid ads every 5 pages. Thank you.

not all assumptions are made equal.
Deep in the land of Mordor, in the Fires of Mount Doom, the Dark Lord Sauron forged a master Assumption, and into this Assumption he poured his cruelty, his malice and his will to dominate all life.
One Assumption to rule them all.
I’m not entirely sure, I’m about to make a post in the correct forum containing all the information I found, and hopefully someone with some intelligence can break it down. I did find some very cool things though in my journeys.
you can reach other conclusions, a person can reach any conclusion they want, doesnt mean its a valid conclusion.
I would feel that it would be a fair assumption that a prospective DU Hull array it would have similar volumetric efficiency as the turret, which we have the improved values for provided by Gaijin and so just take the RHAe of the Turret array divided by the depth of the array (free choice of left or right array) from the turret and multiply the resultant value by the depth of the hull array to get an approximation.
The Block II SE upgrades was only actually deployed for the Turret initially. Said configuration for the Hull was developed and intended to be fielded as weight permitted, but we don’t know if / when it was refit other than it was the intent of the army to do so, and that weight saving were found.
Yes, there is also the “M1A1HA+” sometimes, as well just to fuck with you too. This likely indicates that there are other differences between the HC and HA tanks, that aren’t related to the armor upgrade.
