Yo.
As the title says, for the future I'd like to suggest adding military clothes, headgear and gear/weapons as accessories. I'll make a few examples:
CLOTHES:
Military Uniforms; two for the infantry (the one for the forest/jungle which is the most known, usually having a combination of green, brown and black stains, as well as the one for the barren land/desert, which is usually tan), one for the airforce and one for the navy (blue)
Black Ops Uniform
Officer Suits (possibly with some medals on those and a different one for each military branche)
HEADGEAR:
Military Caps for the forest/jungle, barren land/desert and navy Military Uniforms that were mentioned above, as well as Military Helmets for the forest/jungle and the barren land/desert
Military Pilot Helmet
Black Ops Helmet
Berets (green and red would be mandatory, other colors optional)
Officer Hat
Admiral Hat
GEAR/WEAPONS (as accessories):
Some Rifle of the M16 family
Sniper
Military Backpack
Rocket Launcher
Decorated Military Sword (mainly for the Officer Suits)
All of the suggested cosmetics are meant to be modern. Depending on how much you would be willing to go deep into it, you could also make some retro unfiroms, headgear and gear from some of the historical wars. There is a variety of options.
I came to the idea spontaneously and was actually surprised that nothing like this was made so far. I think it would be a win-win situation for both the staff and the playerbase.

EDIT: Added a sniper to the Weapon section
