I think that one of the weapons will be a AT or hand mortar type gun. Since the last 2 battle pass sets had the Solothurn and the Arisaka mortar. One of the other guns will probably be an smg because it’s been a while since we had a BP smg. The 3rd gun will probably be either a rifle or possibly a shotgun. As for the nations which will get guns I think it’ll be all 3 nations except Japan.
Both the Allies and Germans need a Mortar like this. Let the Allies have captured Ariska’s from the Japanese, and the Germans can have captured RMN-50’s from the Soviets. Four captured ones for each to be exact.
and I know a post about SS misterious grenade launchers: SS grenade rifles a lanciabombe pistol from ww1 and a ww1 british thing who appears in the same museum web I shared
