Parachute Training and Support Unit The Parachute Training and Support Unit (PTSU) was formed in 1965. The primary role of the unit is to provide static line and freefall parachute training to selected elements of the New Zealand Defence Force, mainly the NZ Army. PTSU also provides personnel trained in the operational preparation and despatch of airborne forces by parachute. There are two main types of parachutes used in the NZDF for airborne operations. The T-IOB/D [JOB? 10B?] is the primary conventional round parachute in use for static line operations. It is normally dropped in large numbers and will deliver a soldier and his personal combat equipment at weights up to 150 kg from heights below 1,000 feet. The other parachute in use is the MTI-X "square" or ram air parachute. This parachute is capable of being used in high altitudes and can glide long distances with a fully equipped soldier at weights of up to 182 kg. PTSU was the first in the world to develop these parachutes for military operations in the late 1970's. PTSU is also the home of the RNZAF parachute display team known as "Kiwi Blue".
