There's a mixture of the woodland and desert camouflage IBA (individual body armor) vests. There hasn't been a really concentrated effort to get everyone outfitted with each color since the new Army Combat Uniform (ACU) has been in development practically since the war. Now, everyone will have the new digital camouflage pattern on their uniforms as well as their IBA and ammo pouches and CamelBaks, etc, etc.
Basically it's a cost-saving measure that will eventually be completely fixed across the entire Army.
Besides--haji can barely shoot straight. It takes an act of Allah for him to hit one of our guys (thankfully).
It's sad to think that something as important as a soldier's body armor has to wait as a 'cost-savings measure'. Obviously the coverage.
