Jumpmasters are the expert paratroopers in an airborne unit who train and teach the military techniques for jumping from airplanes. They are responsible for training soldiers who enter Army Airborne School into paratroopers and managing airborne jump operations in airborne units across all branches of services. Military In military applications, jumpmasters are used for static line and freefall jumps. Australia In Australia, jumpmasters are formed and used by the 2nd Commandos Regiment. Jumpmasters from the 17th Special Operations Squadron and 2nd Commandos Regiment conduct jump operation exercises to strengthen interoperability relationship between U.S. and Australian special operation forces. Canada In Canada, jumpmaster training is conducted for the Canadian Forces by the Canadian Army Advanced Warfare Centre at CFB Trenton in Trenton, Ontario. The Queen's Own Rifles of Canada is the only Primary Reserve unit with jumpmasters. Typically those selected for training are very skilled as parachutists. At a minimum, they are senior corporals who have completed leadership training. Separate courses are conducted for static line jumpmasters and freefall jumpmasters (FJMs). United States Role There are two types of Jumpmasters within the US Army; Military Free Fall and Static Line. This explanation will be focused on Static Line Jumpmasters, who are generally just referred to as Jumpmaster. Jumpmasters are easily identifiable in Army formations by their ability to earn an advanced rating for their Parachutist Badge. Senior Parachutists are entitled to a Star atop their wings while Master Parachutists wear a Star and Wreath. In some units Jumpmasters identify themselves to jumpers by wearing a bright red or yellow armband indicating that these Jumpmasters are both qualified (trained in the parachute system being used) and current (within regulations to perform duties as a Jumpmaster). Personnel may be qualified as a Jumpmaster but if they are not current (having pulled duties as a jumpmaster within 180 days) they may not assist the Jumpmaster team or perform duties as a Jumpmaster until completing refresher training. Red is worn by the active Jumpmaster Team. Yellow is worn by any Jumpmasters who are jumping, but not actively participating on the Jumpmaster Team. In addition to this armband, each member of the Jumpmaster Team may wear a fixed-blade knife on their lower leg. The Jumpmaster wears this knife in case a jumper somehow becomes entangled during the exiting process, becoming a towed parachutist, and must be immediately cut free. Other units simply nominate the Jumpmaster team
