The Integrated Individual Fighting System (IIFS), often appropriated as "Individual Integrated Fighting System" in unofficial contexts, is a load-carrying equipment and existence system. It was introduced in 1988 as a possible replacement for the All-purpose Lightweight Individual Carrying Equipment (ALICE) system, itself employed by the United States military since 1973.
The components of IIFS are: the ITLBV (Individual Tactical Load-bearing Vest), later replaced by the ETLBV (Enhanced Tactical Load-bearing Vest); the Grenade Carrier Vest (GCV); the Field Pack, Large with Internal Frame (FPLIF); and the ECWSS (Extreme Cold Weather Sleeping System) sleeping bag, cover, and sleep accessories.
The official name of the vest is ITLBV (Individual Tactical Load-bearing Vest), though it is sometimes shortened to TLBV (Tactical Load-bearing Vest). It is also unofficially known as the 'M-1988 LBV' or 'LBV-88'. The ETLBV (Enhanced Tactical Load-bearing Vest) was a redesign of the TLBV in the mid-1990s. The ETLBV addressed problems with ventilation and access of magazines, adopting mesh panels and slanted ammunition pockets in their place.
Replacing the ALICE and IIFS systems were the MOLLE (modular lightweight load-carrying equipment) and subsequent MOLLE II generation. The MOLLE generations were phased into U.S. Army and U.S. Marine Corps service during the late 1990s to early 2000s.
