PMC can wear camo,it depends of the operation theater, a lot don't but my cousin was in Afghanistan a few years back, worked with some PMC there, some wearing multicam with CB plate carriers, others were civilian style.
To quote him : the first were insanely professional, most of the seconds were complete trigger-happy-dumbasses.
Like in the army : you have pros and zeros... and what I call the "blunder teams", the guys you know will screw up and will indubitably screw up harder than you thought they would.
And obviously gear is a good indicator in some cases.
