The Improved Outer Tactical Vest (IOTV), is an enhanced version of, and a replacement for, the older Outer Tactical Vest variant of the Interceptor body armor, as fielded by the United States Army. The IOTV is compatible with the Deltoid and Auxiliary Protector System (DAPS) components, ESAPI (Enhanced Small Arms Protective Insert), Enhanced Side Ballistic Inserts (ESBI), as well as the OTV's groin protector. The OTV design was considered insufficient and lacking in certain areas, which led to the IOTV's development and fielding. The IOTV is currently produced by Point Blank Body Armor, BAE Systems,〔(BAE Systems IOTV )〕 KDH Defense Systems,〔(KDH Defense Systems IOTV )〕 Protective Products Enterprises,〔(Protective Products Enterprises IOTV )〕 UNICOR and Creative Apparel Associates. The IOTV first saw action in combat with U.S. Army ground combat units in late 2007/early 2008 and currently remains the standard body armor type used by regular U.S. Army ground combat units overseas. ==Technical details== A size Medium IOTV weighs 3.6 pounds less than a Medium OTV vest, while providing more coverage. However, a fully equipped IOTV, complete with all its components (soft armor panel inserts, four ballistic plate inserts (front and back plates and two side plates), collar, and groin protectors) still weighs 30 pounds (13.6 kg), with a Large IOTV weighing about 35 pounds (15.9 kg). The functionality of the enhanced side ballistic inserts, which provide coverage under the arms and down the sides of the torso, is built into the IOTV. The IOTV provides the ability to don the vest in two ways. The first is to simply place the vest over the head and pull down, and the second is to remove fasteners on the wearer's left shoulder, sliding into the vest to the right. To complete the procedure for both methods the wearer then lifts up the front panel of the vest and fastens the waistband, which takes the weight of the vest off the shoulders somewhat, and then fastens the side protection modules. A key design feature for the IOTV is that the entire armor system is able to be released with the pull of a hidden lanyard. The armor then falls apart into its component pieces, providing a means for escape in case the wearer falls into water or becomes trapped in a hazardous environment.〔(Army to Field Improved Body Armor )〕 The hidden release lanyard also allows medical personnel easier access to a casualty, which was one concern that was not addressed with the old Interceptor armor. It also features a grid of PALS webbing on the front, back, and sides for the attachment of modular pouches and accessories. The US Army is looking into supplementing the heavy IOTV with the newer Modular Body Armor Vest (MBAV) and Soldier Plate Carrier System (SPCS) already in service in Ranger and Airborne units. The MBAV and SPCS do provide less armor coverage, but are lighter than the IOTV, thus more suitable for patrol in Afghanistan. The first units began receiving body armor on May 11, 2009.〔(Army stops shipment of lighter gear to field )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Improved Outer Tactical Vest」の詳細全文を読む スポンサード リンク
