On August 28, 1944, General Simonds' requests were granted, and the 1st Armoured Carrier Squadron was formed. The unit was established as four troops of 25 carriers (though only 55 vehicles were then available), with personnel consisting of one commanding officer, four troop commanders, and 100 drivers, and was attached to the 25th Canadian Armoured Delivery Regiment (The Elgin Regiment) for administrative purposes. When engaged in an operation, it would come "under command of various Infantry Brigades in turn." Each carrier had a .50-inch Browning machine gun, and approximately 60% of the vehicles were equipped with radios, however, there was no co-driver to fire the gun or operate the wireless set.
