-Beutepnazer PzKw 747: a T34/76 basicly, vet0 ram replaced with vet1 blitzkrieg, at vet2 it receives armor skirts (unused model exists). Uses panzergrau or some other german skin.
-Pioneer Panzerbüchse 39 Package: costs 60 muni, grants a pair of panzerbüchses for pioneers, locks out other upgrades.
-Supply drop: same as in ostruppen doctrine.
-Hull down: works for the T34 too.
-Sd.KFz. 261: uses 223 model with the pintle mounted machine gun replaced with a panzer commander. Unarmed and doesn't receive veterancy. Has a sight range of 70. Abilities:
--Set forward retreat point.
--Aura: +10% faster cooldown.
--Call in artillery (same as panzer commander upgrade for OKW).
1v1 / 2v2:
The doctrine provides early anti light vehicle measurements via the panzerbüchses and an early generalist tank. The supply drop can always come in handy in emergency. Use the 261's artillery call to force anti tank guns to reposition in the late game.
3v3 / 4v4:
The panzerbüchse and T34 have less impact there. Use the supply drop to aid your allies (typically giving pak 40 to okw). You have two options with the 261: use it as forward retreat point or use it near hulled down tanks, combining their increased range and the scout car's sight to cover a large area.
That sounds really cool! More doctrines where allied and axis factions use stolens weapons is a cool idea
