Yes Paul they look more Army...but I did see and have it cut out of one of our Aussie newspapers where the Marines are on the offensive in 2012, a couple of them are wearing ACH/MICH covered helmets. This is actually why I cut it out for reference material. Perhaps some Marines or our US buddies can confirm maybe the Marines trialled the helmets for possible replacement of the PASGT..
Just found this on 2011 thread: 'Military Photos.Net' "Seen a few photo series lately with Marines wearing MICH helmets in-country, and I'm not quite sure what's up. We still all get issued the LWH stateside, so I don't know if the Corps is beginning a shift towards the MICH or what. They may just be trialing it with one or a few units in Afghanistan and seeing which Marines prefer. Last I hear, MARCORSYSCOM was still participating in the Enhanced Combat Helmet program (with the intent to begin fielding it this fall), which is supposed to have a shape similar to the MICH but provide ballistic protection against rifle rounds, rather than just shrapnel as with the PASGT/MICH/LWH.
