and they are introduced to the jumpers at initial manifest. Duties and responsibilities Jumpmasters are responsible for transforming soldiers who enter Army Airborne School into paratroopers and leading airborne jump operations in airborne units across all branches of services. Jumpmasters make sure each and every paratrooper is proficient at the following airborne operational techniques: Day/Night Combat Equipment Jump Parachute Safety Parachute Deployment Parachute Control Airplane Procedures Static-Line Jump Landing Techniques Duties of a Jumpmaster include: Organizing and mustering their stick or chalk of jumpers. Inspecting all items of equipment prior to loading of the aircraft (to include ALICE or MOLLE pack, Modular Airborne Weapons Case, and any Special Items of Equipment). Inspecting all jumpers for proper donning, fit, and serviceability of their helmet (Ballistic or Advanced Combat) and parachute (T-10D, MC1-1D, MC-6, T-11). Confirmation of in-flight navigation in accordance with flight diagram and Navigation Officer. Safety inspection of the Paratroop Door, Jump Platform, Wind deflector, and Clear to the Rear of the dropping aircraft. Identification of in flight reference points. Proper control of the Paratroop Door during exit. During the above stated activities a fellow Jumpmaster acts as his Safety and assists primarily with Practical Work In Aircraft (PWAC). In addition to the roles of Jumpmaster and Safety, a Jumpmaster may be called upon to act as the Drop Zone Safety Officer (DZSO) or Departure Airfield Control Officer (DACO). The DZSO inserts into the drop zone prior to the jump and is on hand with the pathfinder team to aid the drop aircraft in navigation. The DACO works at the airfield which the jumpers are lifting off from and functions as a liaison with the US Air Force. During major airborne operations, a Jumpmaster known as the Drop Zone Support Team Leader (DZSTL) plays an important role in the operation. The DZSTL represents both the airlift commander and the ground forces commander. He has overall responsibility for the conduct of operations on the Drop Zone (DZ). Considering flight safety as well as ground safety, the DZSTL coordinates closely with the DZ safety officer to observe and evaluate all factors that could adversely affect the safety of the airdrop operation. If radio contact is possible, the DZSTL will pass surface wind information and limited weather observations to inbound aircraft and units, as required. When radio contact is not possible, the DZSTL must ensure DZ markings are properly displayed as pre-briefed to
