"military personnel in camouflage uniforms"
So in this case, Think-geek/El Reg/Gaming Tee shirts, jeans if linux Laptops, suits and maybe El Reg underwear if Windows Laptops and Barrista uniforms and El Reg tattoos around Apple laptops?
Of course, it would sensible plaid shirts, chinos, a nice sport jacket and beards if Unix was on 'em.*
I love Cliches. I'll just get my M65 field jacket...
*Possibly an El Reg bandanna. Not sure about this one.
