Components of the MOLLE System Fighting Load Carrier The Fighting Load Carrier (FLC) is a load bearing vest with modular belt permanently incorporated into vest.[4] Rucksack The MOLLE Rucksack and Rucksack Frame has PALS webbing stitched at places to allow for additional pouches[5] Hydration bladder Plastic 72oz. hydration bladder to supplement the canteen for on-the-go hydration.[6] Modular Pouches Pouches of various utility that can be attached wherever PALS webbing exists. Includes a "sustainment pouch" which holds an MRE.[7] MOLLE Main article: Pouch Attachment Ladder System The term MOLLE is used not only to describe the specific system manufactured by Speciality Defense Systems, but is used interchangeably to generically describe all load bearing systems and subsystems that utilize the woven PALS (Pouch Attachment Ladder System) webbing for modular pouch attachment (though MOLLE is proprietary to Natick Labs, most use MOLLE and PALs interchangeably). Derivatives based upon the MOLLE attachment method (such as the Tactical Tailor MALICE clip system) have also been developed. Any system which utilizes modular attachment methods and is usable with U.S. general issue MOLLE components is often considered "MOLLE-compatible" or is called a "MOLLE" system. More and more non-military manufacturers are incorporating MOLLE technology into outdoor equipment. There are three general modes of attachment in the MOLLE arena, they are "Natick Snap", that uses a polyethlyene reinforced webbing strap with the 'pushthedot' snap for security. There is the polymer "Malice" clip developed by Tactical Tailor as an alternative to the Natick Snap concept, which interweaves like the Natick Snap but terminates in a semi-permanent closure that requires a screwdriver/flat tipped object to disengage. Finally there are a variety of attachments that fall into the "Weave & Tuck" category in which the end of an interwoven strap is tucked into an item's backing after attachment to a vest or pack (Paraclete's SofStrap and Spec Ops Brand's hybrid attachment). The PALS grid consists of horizontal rows of 1" webbing, spaced 1" apart, and reattached to the backing at 1.5" intervals. Evolution of Program and Criticisms The MOLLE system was introduced in 1997. However it did not see widespread issue until after the September 11, 2001 attacks and was used by U.S. troops serving in Afghanistan and, later, Iraq. Early criticisms of the MOLLE system emerged, particularly from the Army. Most of these criticisms have centered on the sustainment-load pack & frame, due to the external plastic frame being too fragile and subject to breaking for the field (since mitigated), that the zippers have a tendency to burst when stuffed full, and that the pack's straps lack sufficient length to easily accommodate body armor.[8] Further, the first generation of this system utilized a "ball & socket" interface between the frame and rucksack belt (which in itself formed the waistbelt of the MOLLE vest). This interface method led to numerous lower back injuries due to the ball (mounted on the frame) missing the socket interface on the waistbelt and impacting the user's body. Subsequent redesign of the SDS MOLLE led to the deletion of this "feature" and thus the vest (FLC) and ruck/frame were separate non-integral items. The pack also switched from the Army's woodland pattern, to the new digital Universal Camouflage Pattern with the introduction of the Army Combat Uniform. The United States Marine Corps wanted a larger load-bearing capability, a smaller overall volume, the ability to carry 60 mm and 81 mm mortar rounds external to the pack, and a simpler overall layout and organization of the system's parts. As of 2004, the Marine Corps has adopted a new off-the-shelf pack design by Arc'teryx and has begun introducing it into the fleet as the ILBE, or "Improved Load Bearing Equipment
