I would like to suggest the Panzerspähwagen (Pz.Sp.Wg.) Ba 10 203(r) mit 2 cm KwK 30 L/50, which as the name implies is a captured BA-10M, however the turret front was modified and replaced to have the gunmantled and armarment of a Pz II Ausf.C.

It would offer a fully enclosed, relatively mobile fully wheeled vehicle with the 2 cm KwK 30, and show the need of the german army, to capture and use everything they got their hands on.

History:
In the USSR, there was a need for fast armored vehicles on wheels (at the time such was the most reliable and with low wear), to quickly go into position, effective for scouting and reach the action or from village to village and in 1927 a 5 year plan was made up, including a heavy armored car,. The BA-10M (M beeing modernised type) were based on the already in service GAZ AAA truck, which was an enlarged Ford AA vehicle. It recived an armored chassis, similar in armor protection (at least from the front) to the T-26 and otherwise to protect against rifle fire from greater ranges. The vehicle was relatively simple and the BA-10 had over 3000 produced. A later improvement was the BA-11, which can also be found in game.

The german army also captured a good amount of them, while generally most were used as is, vehicles also were modified, while T-34 and KW tanks recived german Pz III/IV Cupolas, to improve their visiblity, this spicific BA-10M recived a fully new turret mantlet, taken from a Pz II Ausf.C including its armarment of a 2 cm KwK 30 L/50 and Mg 34.

The original turret was retained and the frontal part and mantled of the Pz II Ausf.C turret was welded to the front, replacing the original mounting. The side plates of the Pz II front were adapted and fixed narrower, to fit to the general turret width.

The modification was made around 1943, and most likely simply due to the need to keep the vehicle effective, the 2 Mgs were replaced by Mg 34 including the hull MG. The original armarment was the 45mm 20-K and 2 7,62 mm DT mgs, both guns which germany did not produce own ammo for, as such reserves were purely made from captured stock. So changing out the gun for a own gun with wast stock and production makes it usable again.

Even tho captured stock of 45mm ammo might be relatively good to get, as the 45mm guns were in use the whole war, there is more to concidder. Effectiveness and general usability. Just like how on the Sd.Kfz.251 and 250 the 3,7 cm Pak L/45 was reduced in service and replaced again by 2 cm guns. While the 2 cm gun is clearly weaker in penetration and size, that was as the war progressed a relative advantage, as the main enemy medium and heavy tanks are quite protected from both guns, the 2 cm guns still had other advantages, beeing Size, weight, duability and beeing automatic. While the 3,7 cm gun was more powerful per shot, the 2 cm guns had either 10 or 20 round magazins, could still fight enemy infantry, reinforced structures, cars, light cars and tanks and otherwise light armor as well as low flying aircraft. In a manual from 1936 it is noted that with normal Ap ground targets are engaged up to 1000m and with he rounds air and ground targets up to 1800m. The same would also apply to the 45mm gun, while even more powerfull than the 3,7 gun with more penetration and he power, however especially in 1943, tanks such as T-34, KW, M3 and M4 would already offer enove frontal protection against the 45mm gun.

The Armarment:
2 cm KwK 30 L/50 and 2x Mg 34 unknown ammo, however usually for Armored cars at least 180 rounds in either 10 or 20 round magazins are reserved.
New gunmantled with -9,5° to +20° elevation, 360° traverse at 16°/sec

KwK 38:(Click to show)

Main Light tank, Armored Car and Truck armarment, often universal rolle against Infantry, reinforced structures, light armored and unarmored vehicles as well as low flying planes.

Generally used pre war till the end of the war, while the 38 was a improved version, reducing weight, increasing reliability and firerate, beeing seen as one of the best of its class in WW2.

The KwK 30 used a L/50 barrle, while the KwK 38 recived the L/65 barrles of the Flaks to simplefy production and supplies, increasing the performance to the 2 cm Flak levels.

Caliber: 20mm

Ammo: 20x138mmB Rheinmetall

Fire Rate: 280 / 450 rpm

Magazinfed: 10 rounds (20 rounds sometimes also available if space allowed it, on Trucks)

Muzzle velocity: 800 - 1050 m/s (L/65)

Barrle length: KwK 30 L/50, KwK 38 L/65

Weight: 64 / 58 kg

Mounts:
Turret mounting: usually -10° to +20°
Sockellafette: -7° to +85°
Hängelafette: -4° to +70°
Schwebelafette: -10° to +60°

Ammo Types: Ap-T, ApI-T, Aphe-T, APCR-T, He-I, HeI-T and HeI-T (m) (And self destruct)

Below characteristics are for the L/65 barrle, in the note in each ammo tap is also for the L/50.


AP:


Pzgr. L'Spur. o.Zerl. (Ph.) (ApI-T) 0,148kg 800m/s 37mm/10m

Note: Used against ground targets. Soft and armored. 3g White Phosphor Core.
Were fully replaced by the empty ones and later .Zerl in the Desert and other hot places, as the Phostphor had a nasty tendicy to self ignite in hot weather.
The Ph. marked ones were standart with the filler, however they also existed with an O. which indicated they didnt have a filler and were only 143g (and 830m/s).
(Velocity for L/50 is 780m/s.)

NOTE: Against ground and air tragets. Soft and armored.
It does NOT have a fuze, the filler is for self destruction, in game it would also explode upon impact when shattering, like the japanese 30mm Aphe or simply after the tracer burns out.
(Velocity for L/50 is 780m/s.)

Note: Only used against heavy armored targets, where the standart Ap ammo does not penetrate.
(There were 3-4 generations, with ever increasing length and slightly weight, to improve stability.)

Sprgr. L'Spur m.Zerl. (Hef-T Sd.) 0,115 900-930m/s 6,2g Pent (10,54g) 5mm/10m

Old design without boattail, prewar replaced by Sprgr. L’Spur W, only remaining stock was used in the war. Velocity for L/50 is 900-910m/s. It is not clear wether a velocity beyond 900m/s can be reached regardless of the projectile weight, with the propellant, as its a high pressure quick burning propellant, with quick drop off.

As always nice Suggestion !

I got one point, there´s NSKK written on the vehicle witch means Nationalsozialistisches Kraftfahrkorps. That opens the question if it was a frontline modification or done in Germany for training purposes ?
The NSKK was the driving school of the NSDAP to make it simple.
