tacticalgeartrade is a Chinese webstore, you've been had.
FYI, USMC don't wear multicam, they wear MARPAT in desert and woodland varieties:
No, I have not been had. I did a bit of research on it before buying, because I liked the kit, although to be honest, even if it was incorrect I'd probably still have bought it anyway. But as it turned out, it isn't incorrect, USMC do indeed wear Multicam on occasion, and even with official permission to do so:
Whilst it is true that the
standard USMC pattern is MARPAT and also true that
Multicam is a DoD US Army pattern, thus technically illegal for other forces to wear it, and against USMC regulations for Marines to wear it (although historically, it's the Marines who've tended to be more picky about who can wear their official patterns), there are several non US Army units which have been granted permission officially by the DoD to wear Multicam in Afghanistan because it is more effective in that terrain, and this includes some Marine units. Amongst the non US Army units wearing Army Multicam with official permission, are the United States Marine Corps Special Operations Command, aka MARSOC - basically the USMC special forces, and the US Air Force Joint Terminal Attack Controllers aka JTAC - basically FACs. So yes, there are Marines who are officially issued a Multicam BDU set, and indeed some US Air Force personnel too, in spite of 'the rules' saying they don't wear that pattern.
Interestingly, there is currently a widespread campaign on Facebook et all, to allow all USMC troops in Afghanistan, and other desert theatres, to be granted similar privileges, with many US people writing to their congressmen about the matter, since Marines have been complaining that Marpat is not as effective as Multicam in that terrain (which it quite plainly isn't when you look at pictures). It is known that some USMC have been wearing Multicam unofficially on operations in Afghanistan, although since it contravenes USMC regulations to do so, naturally they tend to keep quiet about it in the same way that grunts picking up AKs in Vietnam and using those when they found them better suited to the conditions, were hardly going to shout about it to their COs.
In other words, it's like a lot of 'boots on the ground' situations, where the by the book rules go out of the window in favour of practical measures in theatre. A classic example of that is the keffeyah. In the 1991 Gulf War, US Troops were expressly forbidden to wear them, by the second Gulf War there were so many troops ignoring that rule and wearing them anyway because of their practicality in theatre, that the rule got changed and now they get officially issued one, as indeed do UK troops, when deploying to those theatres.
