The 101FC also served with the RAF Regiment. Two 101s were allocated to each Rapier Missile set up. The British RAF Rapier system used three Land-Rovers in deployment: a 24V winch fitted 101 Firing Unit Tractor (FUT) to tow the launch trailer, loaded with four Rapier missiles, guidance equipment and radio; a 12V winch fitted 101 Tracking Radar Tractor (TRT) to tow the Blindfire Radar trailer, also loaded with four Rapier missiles and guidance equipment; and a 109 Land Rover to tow a reload trailer with 9 Rapier missiles and loaded with the unit's other supplies and kit.
