As a supplement to my earlier question, then, was wearing them of any significance? Was anybody fooled by this? How did they arrive at Bastion? In coalition vehicles, beaten-up Toyota trucks, motorcycles, or on foot? How did they move and otherwise carry themselves? Like westerners, or like Afghans? What weapons were they carrying?
I spent seven months watching people, and had no problems differentiating, and that was with, um, "less-than-ideal" Sperwer IR. Clothing had little to do with it. Yes, one could pick out a difference between our uniforms and manjammies, but movement, mannerisms, interactions, and other such indications would allow for differentiation even if both groups were dressed identically.
Somebody could drop a few hundred dollars at CP Gear and just as easily look like a Canadian Soldier who likes aftermarket kit. The only difference between CP Gear's CADPAT clothing and the issued stuff is, really, pockets, and most of those would be covered by vest and/or body armour. Imitations are also available in the older Combat Clothing style, with uncovered buttons, and there are still pers wearing that today.
Anybody could dress like one of us, however few of us would be fooled for more than a few seconds. There would be too many other clues.
