Sorry I'm late
. I've spent a long time looking for more pictures than these but this is all I've found; some seem close but not quite the same, but some of them seem to be the same model.
middle and left seem to be the same
Possibly the one on the right.
The one in the middle has the same color velcro but no Choc chip covering on the cumberbund velcor and thinner shoulder straps made from tan fabric instead of choc chip
The caption for all "Iraqi army soldiers receive marksmanship training on February 6, 2005 by U.S. Marines of the 3rd Battalion 5th Marines at a firing range in Fallujah, Iraq. U.S. officials say the key to an eventual American withdrawal from Iraq will be the readiness of Iraqi forces to take on an insurgency and protect Iraqis."
