The IIFS (''Individual Integrated Fighting System'') was introduced in 1988, to serve as a possible replacement for the All-Purpose Lightweight Individual Carrying Equipment (''ALICE'') employed and fielded by United States Armed Forces since 1974. The IIFS replaces the partially obsolete concept of a shoulder harness, in the style of suspenders, and individual equipment belt design, with the newer concept of a tactical load bearing system that employs a vest. The vest as being the main component, is known as the TLBV (''Tactical Load Bearing Vest''), sometimes referred to as the LBV-88, the M-1988 LBV and later known as the ETLBV (''Enhanced Tactical Load Bearing Vest''). ==History== The IIFS has conceptual roots in combat and load carrying vests designed by Natick Laboratories for the employment and use by United States Navy SEALs during the Second Indochina War. The concept of a load carrying vest is that the weight of the equipment carried by the infantry rifleman is more evenly distributed over the body than with the employment of a load carrying concept of older design. The IIFS load carrying vest, as having been a major conceptual improvement over precursing load bearing systems, was designed to replace the individual equipment belt, individual equipment belt suspenders, and small arms ammunition cases. These components have been an integral part of the All-purpose Lightweight Individual Carrying Equipment (ALICE) system. The small arms ammunition cases continue to be utilized with the IIFS concept, to enable the carriage of additional small arms munitions. Trial variants of the IIFS have utilized both the ALICE water canteen cover and ALICE field first aid dressing case in the M81 Woodland camouflage pattern. The entrenching tool cover had remained unchanged and was also utilized during testing. In the original design, as well as during troops trials, the tactical load carrying vest incorporated panels made of Kevlar, to improve the protection of the infantry rifleman, when worn in conjunction with the Personal Armor System for Ground Troops (PASGT) flak vest. The weight of this prototypic vest was considered to be too excessive to continue to consider this concept. Along with the tactical load carrying vest, a new individual equipment belt was later introduced, featuring a black plastic ITW Fastex quick-release buckle and redesigned adjustment system. The original concept included the use of the earlier renewed individual equipment belt, which featured a grey side-release buckle, commonly referred to, due to its early prestige manufacturer, as the Bianchi pistol belt. It was decided that instead of contracting new individual ALICE components in the M81 Woodland camouflage pattern, that the remainder of already existing and widely available ALICE components will be utilized with the IIFS These being mainly the water canteen cover, the field first aid dressing case, entrenching tool cover and small arms ammunition cases. Like the ALICE system, and along the same design concepts, the IIFS is broken down into a fighting load and existence load. In 1995, due to issues concerning chest and back ventilation caused by the non-breathable fabrics incorporated, the tactical load carrying vest was redesigned, and officially redesignated the ETLBV. No changes to the National Stock Number have been made. The two major modifications have been the slant of the magazine pouches inward, for easier removal of small arms magazines, and the exchange of the fabric panels, which retained body heat, both situated on the front and back, with lighter mesh panels. The IIFS continues to serve the United States Armed Forces to date, though is being rapidly replaced by the Modular Lightweight Load-carrying Equipment (MOLLE). 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「Individual Integrated Fighting System」の詳細全文を読む スポンサード リンク
