NO
Reason's - sorry I have too
I'd say your roster so far is pretty balanced and this change could drastically upset the balance. Secondly, it's called target identification. Everyone will just have to pay attention to detail just like everyone else in the real world. Different armies wear the same colors and the only way to tell them apart is from camo pattern, type of gear/weapons and if you're close enough maybe language/dialect. So I'm down with it being as is.
On the flip side changing it would make target identification super easy.
