Gents can someone give info or throw a link about US MICH 2001 helmets please. It's seams there are plenty of copies from poor to good. I have seen them for sale from some kinda corporations etc. A seller on ebay claimes that they are the one and only, strangely enough he/she doesn't give warranty on ballistic specifications What corporations' helmets are considered G.I.? How to recognise a good mil. helmet? Any general info about 'scalps' also appreciated.
