Unlike the Americans, who saw the M10 as a tank hunter, the British viewed the Achilles as a mobile anti-tank gun.
Perhaps the most successful action of the Achilles was conducted by B troop, 245th Battery, 62nd Anti-Tank Regiment, Royal Artillery attached to the Hamilton Light Infantry during Operation Charnwood. A mixed German force of Mark IVs and Panthers from the 12th SS Panzer Division attempted to retake the town of Buron. The eight Achilles of B troop had set up in an orchard looking south towards Abbaye d'Ardenne and were ideally placed when the Panzers began their counter-attack. In the brief action, 13 German tanks were knocked out and the attack fell apart.
both should be added
