6pdr OQF Mk.III (57 mm)

Description

This is the first tank version of the British OQF 6 Pounder Anti Tank gun, the Mk III being a Mk II with the L/44 barrel length but adapted for tank service. It has excellent reload speed and good ballistic properties but as with most British guns will lack HE filler in their AP ammunition.

Vehicles equipped with this weapon

• Crusader III
• Valentine IX
• ▂МК-IX "Valentine"
• Cromwell I
• M4A5

General info

The 6pdr fires quickly, accurately and with good velocity but due to low caliber and no HE filler you will have to shoot intelligently and precisely to maximise damage to the internals.
