The integrated individual fighting system (IIFS), often appropriated as "individual integrated fighting system" by collectors, is a load-carrying equipment and existence system, introduced in 1988 as a possible replacement for the ALICE (all-purpose lightweight individual carrying equipment) system that was employed by the United States military since 1973.
IIFS components are the ITLBV (individual tactical load-bearing vest) – later replaced by the ETLBV (enhanced tactical load-bearing vest), the 40mm grenade vest aka grenade carrier vest (GCV), the FPLIF (field pack, large with internal frame) pack, and the ECWSS (extreme cold weather sleeping system) sleeping bag, cover, and sleep accessories.
The vest is known officially as the ITLBV (individual tactical load-bearing vest), though it's sometimes shortened to TLBV (tactical load-bearing vest), and unofficially referred to as the 'M-1988 LBV' or 'LBV-88'. An upgrade to the vest, the ETLBV (enhanced tactical load-bearing vest), was a mid-1990s redesign for the TLBV to address problems with ventilation and access of magazines, now having slanted ammunition pockets attached to mesh panels.
Replacing the ALICE and IIFS systems, the MOLLE (modular lightweight load-carrying equipment) and subsequent MOLLE II generation were phased into U.S. Army and Marine Corps service during the late 1990s to early 2000s.
