a range of 10 yards, though was penetrated by a second closely spaced shot of 9mm Federal FMJ after the first. Appearance The PASGT vest is typically covered with woodland pattern nylon fabric, either the ERDL pattern or U.S. Woodland. A very limited number of vests were made in olive drab, but only woodland versions were issued to U.S. forces. Like the PASGT helmet, camouflage covers were available to be worn atop the vest in various patterns. Early camouflage covers were in DBDU but later came in the DCU pattern. Development The PASGT vest was designed in 1975 and was tested by in the late 1970s before being fielded in the early 1980s. U.S. Navy Flak Jacket In January 2000, the U.S. Navy began using a derivative variant of the PASGT vest known as the "U.S. Navy Flak Jacket Mk 1, Mod 0". This vest was still being used by the U.S. Navy as late as April 2017. The USN Flak Jacket is sage green or brown in color. Although this vest is quite similar in appearance to the PASGT vest, it actually is a different model of vest altogether. Accessories and usage In order to provide protection against high velocity bullets, the PASGT vest was, in 1996, combined with the Interim Small Arms Protective Overvest (ISAPO) pending the adoption of Interceptor body armor. The ISAPO weighed about and consisted of a carrier to hold two protective ceramic plate inserts. A PASGT armor system with overvest weighed more than and was criticized by many U.S. troops as unacceptably cumbersome in combat. The ballistic fill consists of 13 plies of 14 oz. water repellent treated Aramid (Kevlar 29) fabric. The inner and outer cover, shoulder pads and front closure flap of the vest are water repellent treated 8 oz. ballistic nylon cloth. While it had been phased out as frontline body armor by the start of the Iraq War in 2003, the PASGT vest saw some limited wear and usage by U.S. military personnel during the early stages of the war, where it was worn behind the frontlines by rear-echelon support personnel and navy sailors such as Seabees. Some U.S. Army soldiers used old PASGT vests as makeshift armor for their vehicles in the absence of actual up-armor kits. Replacement The PASGT vest was succeeded in U.S. military service by the Outer Tactical Vest of the Interceptor Body Armor system, which
