i think it would be neat to add the guard marines as they did exist it would cool to also give them maybe a ptrs or possibly some avs-36 as no soviet units have them it would be cool to see that gun or give them all svt-40s and better experience

We could also have some german marines not used much during ww2 but would be cool to have them as a unique unit for the germans they were called Marines stosstrupp
kompanie and used during the battle of berlin maybe give them some satchel charges and sabotage equipment a few stgs or g43s and maybe some type of light machine gun
