It could have a selection of combat uniforms (Say, Pixelated, DPM, Multicam, and the MACO ones from Enterprise).
Uniforms would be boots, jacket, shirt (as a seperate varient for each uniform) and berets or helmets.
If it was going to be a set on the C-Store, it could also contain a rifle (Maybe something from 21/22nd century that has been modified?).
Also, it could maybe include a new kit, I'm thinking: [Tactical Kit - Soldier]
Powers: Frag Grenade
This will more than likely fall on deaf ears since it's for the KDF, but moar costumes over there would be very nice, there's alot of female costumes seen in show that would do very nicely and those longcoats the npcs have would be great.
