Quickly threw some stuff together; couple new gun models (StG 44, Gewehr 43) and some modification of German Inf texture and voila.
Waffen SS squad will come with:
3 x StG 44 Assault Infantry (also armed with geballte ladung “bunched” heavy grenade)
4 x Gewehr 43 Carbine Riflemen
1 x Gewehr 43 “Marksman” (fires faster than a Sniper, but shorter ranged and less powerfully and far less pinning)
1 x Panzerschrek
1 x MG42
