Ghillie camo suits

[Combat Wombat]

it depends what you mean by 'at a distance' . most uniforms are cammo that limit you being spotted 'at a distance'. We cam up faces, hands and weapons but do carry identity at all times. (The Aussie uniforms (baked bean design) has items of identity that really can't be seen until you are standing face to face - especially rank flashes - black marks on the chest slide). we use camoflage in ambushes and when advancing towards enemy positions. special forces just take more care and use more skill than the average grunt.. (anyhoo, SF are always easy to spot- just look for the gigantic wrist watchs moving through the scrub!)

same deal with snipers, they hide under camoflage -natural or man made, in uniform and have identifying badges - observable at a distance ( a metre or so? ) and so comply with convention.
