Like the A9, of which it was an extension design the A10 had armour of 14mm and again was the result of some rather muddled thinking, having a maximum speed of 18mph and initially 2 machineguns in the front hull, soon replaced with a single Besa in addition to the co-ax machinegun. The main gun, the 2pounder, was a fine gun for its day, and was the only positive feature. The A10 was designated as a ‘cruiser’ tank and had several innovative design features, but was rather unreliable. During the campaign in France the weakness of the armour and unreliability proved fatal for the design, and of the 175 tanks built, the 30 designated CS (Close Support) tanks with the 3.7” howitzer proved of little value either to the crews or the infantry that they were supposed to support.
The A10 was involved in battle in France, Greece and the Western Desert, but was not beloved of its crews.
