Only Riflemen?

[xxpagxx]

When I want to replace lost members in a squad during the unit select, there is only a choice of different riflemen and tank commanders. No SMGs, bazookas, etc.
Is it supposed to be this way? Should I just procure the whole squad again if I need the special roles?

It is supposed to simulate only being able to get new recruits but you can edit the files to allow you to add each unit type. As for whether you should get a whole new squad or not its up to you, I don't mind picking up a German MG if I lose my gunner.

Yes it is supposed to be that way, although I'll add some more choices for the next version.
Specialists will be rather overpriced though, and veterans and officers won't be available.

Yup, thats the idea.
