The Lightweight Environmental Protection (LEP) is an insulation subsystem developed under the Special Operations Forces Personal Equipment Advanced Requirements (SPEAR).The system is designed to be individually configured based upon mission, terrain and climate requirements as well as personal preference.

The Protective Combat Uniform (PCU) is an interchangeable 15-piece, 7-level ensemble (the original block 0 configuration) that can be worn in layers appropriate for the mission.The PCU replaces the LEP.

The SPEAR Body Armor/Load Carriage System (BALCS) consists of body armor, an equipment load carrying subsystem, and a backpack subsystem.

The Modular Integrated Communications Helmet (MICH) began development in 1997 as part of the Special Operations Forces Personal Equipment Advanced Requirements program at the U.S. Special Operations Command. The MICH provides the Special Operations Forces the flexibility to tailor the communications capability of the helmet to the mission using one modular system.

Special Operations Forces Personal Equipment Advanced Requirements (SPEAR) is the United States Special Operations Command's (USSOCOM) modernization effort for the joint (Army, Navy, and Air Force) Special Operations Forces (SOF) operator. SPEAR focuses on four areas of improvement in personal equipment.These four areas produce a modular equipment system whichfocuses on mission tailoring, enhanced survivability, andenhanced mobility while reducing weight, bulk and heat stress.
