It would be pretty cool to have a skin item for the soldiers like:
Weaponry-Perks-Skins:
Skins:
Helmet
Body
Gloves
Boots
Weapon (these can be weapon specific skins and not generalized)
And the skins you can get from drops from the game as well. That way you can get your whole squad looking the same since sometimes they look different if you take soldiers from other squads and move them around. Or you can just make squad leaders look different and stuff.
Also having more control of your squad, it would be nice to be able to tell 2 soldiers to stay in a certain place while having the others do something especially when you have 3 snipers and the rest troopers. Being able to keep the snipers back would be nice. Also being able to tell them to use turrets.
Having class specific AI have different combat ranges.
A sniper with a scope should agro from farther away then an assault with an SMG. Seems kinda dumb how my snipers with scopes have to be within SMG range in order to start shooting someone.
