QF 2-pounder (40 mm)

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

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Depending on the tank, the tactics available to you differ. The QF-2 Pounder has a rapid rate of fire and is found on faster chassis, such as the SARC MkVI (2pdr), Daimler Mk II, and Tetrarch I. The faster speed and smaller profile of these platforms, along with the decent penetration of the cannon itself, makes it suitable for flanking and killing tanks. It can also be used in brawling, though the Crusader (Family) tanks may not be suitable for this type of combat due to their poor reverse speeds and low amounts of armor.

On Heavy tanks, this is somewhat different. Matilda (Family) and the Churchill I tanks can absorb gunfire and return it. While this can include getting kills, it also can involve disabling enemy tanks in ways such as hitting their tracks, disabling the gun, or doing damage to the propolsion systems like the transmission or drive.

Be warned that using the QF2 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 round
• Quick reload
• Decent muzzle velocity

Cons:

• Lack of explosive filler on most shells means multiple shots could be needed to take out a target
• 3 of the 4 available shells 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.
