 Some Canadian and British infantry divisions had been temporarily equipped with M7 Priest self @-@ propelled guns for the D @-@ Day landings , which had been replaced by towed Ordnance QF 25 pounders . Simonds had the Priests converted into Kangaroo Armoured Personnel Carriers , which would allow infantry to follow the tanks closely on any terrain . Permission was first requested from the Americans , from whom the M7s had been borrowed , to convert them into APCs .
