The Morris Commercial C8/Anti Tank (AT) Mark 3 Artillery Tractor was used as the towing vehicle for the 17 Pounder Anti-Tank Gun.
Already in use with the British Army, the Morris was converted for airborne forces use by removing the canvas roof and supports, along with the sheet metal sides, doors, tail board and tool boxes. These modifications reduced the overall weight to 4.5 tonnes, allowing transportation with the 17 Pounder, crew and ammunition, in the Hamilcar glider.
During Operation Market Garden the Morris was loaded with 15 boxes of ammunition, each containing 2 armour piercing shells, for the 17 Pounder.
The Morris proved unreliable during the operation and was withdrawn from service shortly afterwards.
