3-color desert IOTV armor cover not originally found with chest rig and jacket. It was added since soldiers would commonly wear the chest rig over their armor (see use photos).
Fire resistant tan aramid Combat Flight Suit/IABDU jacket for protection against improvised explosive devices during vehicle and street patrols. These were used as a stopgap measure before fire resistant ACUs were widely issued. Modified with black velcro for flag and identification patches. Jacket tag has an error since there is no camouflage pattern on the jacket.
Buckle date is March 2005 (arrow points to 3, or March; 05 in circle is 2005). This is from a second production run since it has 2 front quick release buckles. Back pouch is for a camelbak hydration bladder. The first production ones only have 1. Around 2000 of these chest rigs were originally made for the 325th Airborne Infantry Regiment (“Falcon Regiment”) in 2004 for an Afghan deployment.
