 The tank 's design flaws , combined with the decision by the War Office not to use light tanks in British armoured divisions , ruled out the use of Tetrarchs in the North African Campaign . As a result , the majority of the tanks remained in Britain , although 20 were sent to the USSR as part of the Lend @-@ Lease program . In early 1941 , the Royal Armoured Corps formed three squadrons for use in overseas amphibious operations , one of which was equipped with Tetrarchs . In May 1942 , a small number of Tetrarchs formed part of the British force which participated in the invasion of Madagascar , and , in June 1942 , Tetrarchs were attached to the 1st Airborne Division after it was decided that the design allowed its use as an air @-@ portable light tank to support British airborne forces . The Tetrarchs were transported and landed in specially designed General Aircraft Hamilcar gliders . A lack of gliders prevented their participation in the Allied invasion of Sicily in 1943 ; instead they were attached to the new 6th Airborne Division and became part of the 6th Airborne Armoured Reconnaissance Regiment .
