| Notes | The Achilles was the US designed M10 tank destroyer modified to carry the 17 pdr anti-tank gun, this replaced the usual 3in M7 gun. The 17 pdr packed a harder punch then the 3in and could engage the German Panther and Tiger tanks at ranges over a 1000m. It gave the British anti-tank batteries time to move and repel German tank attacks before standard towed guns could be brought into action. As with the Archer the Achilles was issued to anti-tank batteries of the Royal Artillery and saw action in North West Europe and Italy. |
