I agree with what marvel said on this.
1 thing to add is that sub units depend on the agreement that is made to begin with between the battalion and the high command. Some sub units had made agreements (even though I think agreements should be open for re-negotiation) on whether it is a limited number, lore character based group, or just a mini version of the battalion with a couple of lore characters tossed in to give it "flavour".
I think this is a fine idea as long as you A. think it will improve DS and CG, and B. have the best most fleshed out plan as possible for it.
Personally I think that DS should get the heavy shield instead (since we don't even use it on the server for anything) and CG should try to get riot troopers back and give them riot shields and a modified version of the old electro staff that would work like the stun stick.
I won't vote on this just yet, however I probably will +1 it.
P.S. I gotta say, the paratroopers, marines, BARC troopers, and whatever the one in the third picture got that drip.
