Improved Load Bearing Equipment



The Improved Load Bearing Equipment or ILBE is a United States Marine Corps program that includes individual load carriage equipment, individual hydration systems (Source One Hydration) and individual water purification. Since the rucksack was the first part of the program issued to Marines, the ruck is commonly referred to as simply "ILBE". The ILBE ruck was designed to replace the existing ALICE and MOLLE packs. The ILBE is designed by Arc'teryx's Law Enforcement and Armed Forces "LEAF" program and manufactured by Propper Inc. The backpack is made from Cordura 725 denier fabric, with MARPAT camouflage pattern printed onto it. The pack is also covered with a PALS grid, for the attachment of smaller modular pouches. It includes a main pack, a detachable assault pack and a 100-ounce (3 liter) water reservoir. The ILBE can hold up to 120 pounds and has room for 60mm and 81mm mortar rounds outside the main pack. Specialized bags for corpsmen and reconnaissance units are also available.

Because the ILBE was fielded before the creation of the Modular Tactical Vest, the pack does not integrate well, and this stress with body armor can cause discomfort and injury. Marine Corps Systems Command announced a replacement was forthcoming in 2009, with possible replacements including two entries from Mystery Ranch, Granite Gear, and the Army's improved version of MOLLE. In 2011, the Corps finished testing and released a solicitation for prototypes under the name "USMC Pack", outlying design requirements that are similar to improved MOLLE.
