General info

The 'A13 Mk.II in the garage.

The Mark IV A13 Mk II is a Rank I British light tank with a battle rating of 1.3. Featuring the QF 2-pounder as main armament coupled with good mobility, this vehicle is a typical light tank and plays as such.

The main purpose, usage and tactics recommendations

General play style

This vehicle's role it that of a light tank in the truest sense, sporting an acceptable gun, great mobility and virtually no armour to speak of. The main difference from the Mk II to the Mk I is that the former has a better turret protection, adding 0,8 tons of steel without hindering mobility.

This tank has a very active playstyle and should not be used in the front lines. Instead, use your mobility to your advantage: Spot, flank and provide artillery support for your teammates, blind your enemies with well-placed smokes screens in key avenues. Make sure to only target secluded enemies in flanking tactics so you can take full advantage of the element of surprise and outflank your opponent. Never expose yourself for too long because even anti-aircraft guns are a potential threat to your unangled armour. The QF-2 pounder has an awfull long range accuracy so you must get close to your ennemies to actually land a shot where you expect. Load up this agile (but reluctant) cat with ammo and flank your enemies with a constant flow of bullets.

Vehicle characteristics

This tank is a good representative of later rank 2-3 british tanks: good mobility, flat and thin frontal armour, bad reverse speed and minimal post-penetration damage.

Driving Even though the A13 has good mobility, it sometimes feels weird: it looses speed on turns, does not accelerates quite as fast as it's overpowered engine(38.19 HP/ton, stock) should provide it and hill climbing feels hard. All of these flaws come from the gearbox, which has bad and uneven ratios, resulting in a kick when changing speed. Knowing that, you should always keep an eye on the "gear" counter top-left of your screen (activate it in the option menu) since it provides you crucial information on how your tank will react to your commands. With a bit of practice, one should swiftly masters these peculiarities.

Shooting Since the QF 2-pounder is used on most tanks of Rank 1, it's important to know it well. This cannon has a major disavantage at distances since it's bullet loose around 20mm of penetration for each 500m it travels, which is a lot. As if this was not enough, it has poor accuracy, even with Adjustement of fire, hence, one should target large components (crewmens, engine, transmission), of the ennemy or, as distance increases (500m or more), the general center of the foe. Firing it, you will easily notice it's last but not least flaw: it does almost no post-penetration damage, which means you will need to snipe crew members one by one. Combine this difficulty with a bit of distance and this task can prove tricky pretty quick, sometimes leaving the ennemy enough time to resplenish it's crew before you finish it off.

On the other hand, this cannon has 5 major advantages: reload speed, close-quarter penetration, a primitive stabilizing system, LOTS of ammo and awesome gun depression. It's fast reload speed allows it to compensate it's poor accurcy: misssed a shot ? why not take another even before you can reposition ! Close quarter penetration, one of the best at it's tier, is also a plus: your ennemies will only block you shot if you happen to hit a steep-angled plate of armour. This tank has good mobility ? nice !, it can fire on the move too, at low speeds and on relatively flat road though but still, it is much more precise than the comparable BT-7 with its 20-K. Last but not least, small bullets means more bullets: the A13 can bring up to 87 bullets into the game, much more than you need to knock out 3-4 tanks, which means you can try to suppress an ennemy and keep it into cover by constantly firing near it (at this rank, this tactic can prove effective against new players). Finaly, its good gun depression enables it to fire over hills, peeking only it's small turret, shooting and disapearing swiftly. Use these features cunningly.

Others Since the addition of smoke in War Thunder, light tanks have it easier. Use your forward-lauching smoke to create a wall of smoke in a strategic place. It can be used to cover your allies, when capturing a point, flanking in a street (urban environnement),

Tactics

If it was not clear enough, there it it: the A13 is a flanker, use your speed to outflank ennemies and pray not to be spotted before you can land a few shots. at this BR, it's common to fight against larger and more armoured targets

Specific enemies worth noting

It is notable, to avoid attacking tanks with a lot of internal space and crowed tanks. Knowing that, LVT(A)(1), T-28 and the less common T-35 are your worst nightmares. Do not fire at them (unless helped) since they can soak up fire very well.

Counter-tactics

Especially in low-tier battles, watching the flanks is really important since most tanks rely on mobility to avoid being killed on the first shot. Specifically, the A13 Mk I has a very weak side armour, which you can destroy with MG at ranges 500m or lower. Also, since this tank has it's mobility for only protection, shooting the exposed driver should provide you with an easy kill. Do not bother to spend too much ammo on this tank since it has 4 crew members. One could also turn its engine block to this foe to soak its non-HE shells, leaving little chances of igniting the fuel and protecting crewmens in the hull.

History of creation and combat usage

Development

The British development on their cruiser tanks advanced greatly with the implementation of the Christie suspension system, which they acquired from an American firm. The tank underwent a development program under the name Cruiser Mk III (A13) and the first accepted variant for the military was the A13 Mk.I. The Mk.I featured 15 mm of armour, a 2-pounder cannon, and a Vickers machine gun as its coaxial armament. An order of 65 of these tanks were asked for in 1939 at the Nuffield Mechanization & Auto Limited, but only 30 were made before the a decision was made to upgrade the existing model with more armour and different armament.

The redesigned cruiser tank, the A13 Mk.II, Cruiser Tank Mk IV, had a new armour thickness of 30 mm and additional sloping armour was put onto the sides and rear of the turret. The Vickers machine gun used as the coaxial armament was also replaced by the BESA machine gun, a licensed Czech ZB-53 machine gun, due to issues with the Vickers gun. Around 225 to 665 A13 Mk.II tanks were produced from 1940 until late 1941.

Combat Usage

The A13 first saw combat in the Battle of France under the British Expeditionary Force in 1940. The A13 encountered many trouble during its employment, the crew have little to no training with the new tanks due to their rushed adoption into service, the tanks were in poor condition and some were even missing parts. The A13s were used in the 1st Armoured Division, but many were either destroyed by the superior German armoured forces or abandoned at Calais during the evacuation of Allied troops at Dunkirk, which forced the units to leave behind their heavier equipment.

After the disaster at France, the A13 were still used to support the war. Some were sent to Greece to support their defense against Germany in the Battle of Greece, but a majority were sent to North Africa as part of the Western Desert Campaign near Libya under the 7th Armoured Division. Compared to the time in France, the A13s in North Africa fared much better, ironing out most of its initial defects, and was even more suited to the environment than other tank designs. The A13 was popular with the crew for its high speed, reliability, and a powerful 2-pounder cannon that could engage a majority of Axis tanks in 1941. However, there was an insufficient number of A13s available for use, so tank units were mixed with the faster cruiser tanks and slower infantry tanks, which caused tactical and logistical difficulties trying to accommodate all of the tanks. Another deficiency with the tank and every other British tank with the 2-pounder was the lack of high-explosive shell issued to the tankers, which made them vulnerable to anti-tank guns, which caused a majority of British tank losses in the North African Campaign. Still, the A13 fared very well with its armor and armament until the late 1941 where better armored Panzer IIIs and Panzer IVs began to appear on the battlefield.

Due to its growing obsolesce on the battlefield, the A13 was replaced in 1941 by the better armored A15 Crusader tank.
