There are a lot of tank destroyers available now so what I decided to use them for was an anti-tank gun similar to the AAA guns except that offensively they operate just like a tank. A3/ D 3D6@1 -OR- 3/ M2/ C8
Same for the panzerfaust Inf but with modification. A1/ D1D6@1 -OR- 2 (like regular Infantry)/M1/ C4.
The rifled field cap guys looked like perfect conscripts A1/D1/M1/C2
I have some others too.
