| Notes | Main Anti-Tank Gun at the start of the war and saw action in every front, it was heavy for a gun of this calibre, mainly due to the carriage, it was capable of all round traverse when dismounted, but could be fired with wheels still attached, but with limited traverse. Gradually phased out with the introduction of the 6 pdr but remained in use against Japanese armour in the Far East. |
