Prior to the attack on Tobruk in January 1941

One side benefit of the attack on Tobruk being delayed was that the 7th RTR now had 18 running Inf.Mk.II's instead of only 13. The A Squadron of the 6th Australian Divisional Cavalry had been equipped with captured Italian medium tanks, at General O'Connor's orders. 16 tanks, mostly M11/39's but also a few M13/40's were put into running condition. The tanks were marked with big white kangaroos. A squadron was split into three squadrons and reinforced with men from infantry battalion carrier platoons. They were named Dingo, Rabbit, and Wombat. During the night of January 17th, a nasty incident occurred where the brigade major and other officers Brigadier Allen's 16th Brigade and several scouts from were wounded on Italian booby traps. They had gone out to mark the start line, when they ran into trouble. This is based on the account in Gavin Long's book To Benghazi.
