Yes, but thats all prototypes, single models, extreme specialists or early war junk.
Nothing that would not be obliterated by stock soviet units really, but I can't deny I'd like to see army centered around light vehicles and lighter tanks(P3s and shit) with lightly armored TD support for AT.
There´s actually enough stuff for a new German faction that is up to date in 1944/45. No prototypes or early war junk needed.
Hetzer - partly better armored than a StuG and with a remote controlled MG on top.
Nashorn - Elefant gun on Panzer IV chassis.
Jagdpanther - Elefant gun on Panther chassis.
Nebelwerfer - a classic.
Panzer III Ausf. N - by 1944 this was used to fight off infantry with 80mm armor and a stubby 75mm gun.
Wirbelwind - Panzer IV chassis with quadruple flak.
88mm Flak 36 - a classic.
Hummel/ Wespe - An equivalent to the 152mm on tracks, 105mm Priest respectively.
Jagdpanzer IV/ L48 - Similar to the StuG. Worse gun and slightly less armor than the current L/70 variant.
Most of this stuff would still perform better than allied stuff. Don´t act like there´s nothing left.
