The 40 mm QF 2-pounder on the A13 Mk I (3rd R.T.R.) gun mantlet.

Description

Following the 1935 budget in Britain, the Government decided to standardise the armaments employed by both the Royal Tank Regiment and anti-tank gun companies to be identical. The first tank to utilise this gun was the Cruiser Mk. I (A9) which entered service in 1938. This tank, whilst not in the game, saw service in North Africa and France alongside other tanks such as the A13.

Seeing action during the Phony War and the Retreat to Dunkirk, it was first used on the battlefield by the Belgian Army, however many of the guns that were produced had to be abandoned following the evacuation of Dunkirk. Stockpiles in Britain would eventually be distributed to the Army before they were phased out for the QF 6-pounder, and the remaining guns were sent to Home Guard Anti-tank sections across the United Kingdom.

The gun was proven to show its effectiveness against the early Panzer IIs and Panzer IIIs however it could also pierce elements of the later Panzer IVs until the E variant.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

The QF 2-pounder has a rapid rate of fire and decent penetration. This makes it the ideal candidate for brawling or flanking manoeuvres. Using the QF 2-pounder for long range fire on enemy tanks is ill-advised: the penetration drops sharply the further away you get, and there are better options in your arsenal, such as the QF 17-pounder (76 mm). If you must engage at long range, consider using the Shot Mk.IXB or the Shot Mk.1 APHV/T.

Pros and cons

Pros:

High-penetrating APCBC round
Quick reload
Decent muzzle velocity

Cons:

Lack of explosive filler on solid shots means multiple shots could be needed to take out a target
3 of the 4 available armour-piercing rounds lose penetration very quickly over range
APHE shell is only useful at very close range and often bounces

History

The gun proved its effectiveness against early Panzer IIs and Panzer IIIs and proved effective even later against more advanced enemies where it could also pierce elements of the Panzer IVs until the E variant arrived to the battlefield.

Examinations of the gun on angled surfaces showed good results in the 1936 tests.^[1]

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
