Ordnance QF 6-pounder

The Ordnance QF 6-pounder was Britain's "medium" anti-tank gun in WW2. 57mm in calibre, it was considered a very high-velocity cannon even amongst its contemporaries, and boasted incredible penetration. Not even Soviet heavy tanks were safe from its supersonic, whistling shot. Later on, tungsten-cored APDS ammunition was designed for this cannon, giving it equal or superior anti-tank performance to even Germany's infamous FlaK cannons. A ton exist within Oceanyka, where it continues to be an effective tank cannon and anti-tank artillery piece.
