This manual contains basic and advanced training and techniques for static line parachuting. It is designed to standardize procedures for initial qualification and training of personnel in their duties and responsibilities in airborne operations. The jumpmaster, assistant jumpmaster, safeties, DACO, DZSTL, and DZSO occupy key positions in airborne operations. The initial training and qualifications of these personnel designated to occupy those critical positions are contained in this manual. SOF unit personnel must meet the requirements for static line parachuting contained in this manual as well as provide special training and instruction for nonstandard equipment, aircraft, and personnel procedures. These procedures are documented in FM 31-19, FM 31- 24, FM 31-25, and USASOC Reg 350-2. Individual service components that deviate from this manual due to unique mission requirements will use approved procedures, techniques, equipment, and equipment-attaching methods specified by their respective service.
