The Corpsman Assault Pack (CAP) is an improved design to replace the previously fielded MOLLE Medical Bag.
The Corpsman Assault System (CAS) is specifically intended to provide the Corpsman with a load carriage system that fully integrates with the USMC Pack and currently fielded body armor systems.
The MOLLE medical bag was designed to carry a mix of medical supplies and equipment that could be customized for specific missions.
The MOLLE Combat Medic Set consists of a medic bag and eight external medic modular pouches (four each for the vest and the bag). This set is duty-specific and is issued in addition to the rifleman set.
The Improved MOLLE Medic Set (IMMS) is a redesign of the MOLLE Combat Medic Set. It accommodates the changes in Tactical Combat Casualty Care (TCCC) doctrine and enable combat medics to carry additional life saving medical supplies.
