The Advanced Combat Helmet (ACH) is the United States Army's current combat helmet. It was developed by the United States Army Soldier Systems Center to be the next generation of protective combat helmets for use by the U.S. Army. The ACH is derived from the Modular Integrated Communications Helmet. == History == The Advanced Combat Helmet was fielded in 2003 by PEO Soldier to replace the PASGT helmet.〔 In 2007 the Army introduced a ballistic "nape pad" that attaches to the ACH's rear suspension system. 430,000 were to be issued in the Rapid Fielding Initiative (RFI).〔 Beginning in 2008, the Army's Program Executive Office Soldier outfitted soldiers of the 101st Airborne Division and 4th Infantry Division bound for Iraq with helmet-mounted sensors designed to gather data on head injuries caused during Improvised Explosive Device (IED) detonations. The data collected will help with the design of improvements to the MICH's suspension and chin strap systems.〔( Army.mil - Helmet Sensors, Improved Armor Helping Soldier Survivability )〕 In 2006, 102,000 helmets were ordered from ArmorSource, of which 99,000 were delivered when the contract was fulfilled and properly closed. In May 2009, 55,000 of these were in storage and 44,000 were in use U.S. Army, Navy, and Air Force personnel. The 44,000 helmets in use by service members were recalled by the U.S. Army in May 2010 due to potentially defective materials being used. No proof of defective materials was ever established nor evidence of any wrongdoing by the contractor. In May 2009, 34,218 ACHs made by the Gentex Corporation were recalled. Certain screws attaching the chinstrap and other parts to the helmet did not conform to specifications in the contract. The screws failed ballistics tests at extreme temperatures. Gentex alleges its subcontractor had fabricated compliance certificates for the screws.〔 A MultiCam cover for the Advanced Combat Helmet began fielding in late 2009 for soldiers deployed in Afghanistan. The ACH and Lightweight Helmets will eventually be replaced by the Enhanced Combat Helmet. 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「Advanced Combat Helmet」の詳細全文を読む スポンサード リンク
