Description
The Tank, Cruiser, Mk III (A13) (3rd Royal Tank Regiment), also designated in-game as the A13 Mk I (3rd R.T.R.) is a premium rank I British light tank
with a battle rating of 1.0 (AB/RB/SB). It was introduced along with the initial British tree line in Update 1.55 "Royal Armour". At some point, it was given for free if you chose Britain as first nation when you started the game.
General info
Survivability and armour
Armour type:
- Rolled homogeneous armour (hull, turret)
- Cast homogeneous armour (Gun mantlet)
Armour | Front (Slope angle) | Sides | Rear | Roof |
---|---|---|---|---|
Hull | 14 mm Front plate 14 mm (0-62°) Front glacis 14 mm (64°) Lower glacis |
7 + 7 mm | 14 mm (0-62°) | 14 mm |
Turret | 14 mm (0-15°) Turret front 14 mm (1-63°) Gun mantlet |
14 mm (21°) | 14 mm (2°) | 14 mm |
Cupola | 14 mm | 14 mm | 14 mm | 14 mm |
Notes:
- Suspension wheels and tracks are 15 mm thick while the torsion bars in between the side armour are 10 mm thick.
- Hoisting points and optics covers are 14mm thick.
- The sides of the hull benefit from spaced armour (2 x 7mm spaced circa 10 cm apart) but the thickness of the plates is too poor to properly act as such: HEAT and HE shells have no problem defeating it.

Armaments
Main armament
Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}
. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Notes:
- To minimize the risk of ammo rack detonation, keep racks 1 to 14 empty (31 (+56)). This will guarantee the center hull is empty of shells.

Usage in battles
This vehicle's role is that of a light tank in the truest sense, sporting an acceptable gun, great mobility and virtually no armour to speak of.
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 non-angled armour. The QF 2-pounder has an awfully long-range accuracy so you must get close to your enemies 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.

Pros and cons
Pros:
- Good gun for its rank
- Fast
- Slim target
- Has a "lock", which is a primitive form of stabilisation; this makes stopping and firing a useful tactic as the 2-pdr doesn't bounce as much as a non-stabilised gun
- Brings lots of ammo to the fight (87 rounds max)
- Has forward-launching smoke launchers
- Coaxial machine gun
- Good horse-power per ton ratio
- Decent turret sewing rate
- -15° gun depression
- Four crewmen and a three-man turret
- Quite a fast reload, makes finishing off a target both quicker and easier
- Very effective in its historical role, a flanker and scout
Cons:
- Next to no armour
- Barely any response from the engine
- Loses speed when turning
- The ability to carry almost 90 rounds comes at a cost, this cost is that the ammunition is very hard to miss and thus, the A13 series suffers from frequent ammunition detonations
- Wiggles when trying to turn on 5th gear
- Regular machine guns can penetrate side armour
- The coaxial machine gun is a Vickers which, compared to other Rank I machine guns, has an incredibly slow fire rate
- Not effective at anything other than how it was historically used; ill-advised to brawl or support heavier vehicles
History
Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main
template. Be sure to reference text and sources by using <ref>
, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===
, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
