-Development for this tank started in 1937 by Vickers-Armstrongs privately as the '''Light Tank Mk VII''' and nicknamed the ''Purdah''. The trials tested the tank's ability to act as a "light cruiser", but this failed as the [[A13 Mk I|A13 cruiser]] was much better at the task. Thus, it was suggested that the Mk VII be tested as a light tank instead and production to be started for the trials. The Tetrarch was first issued in November 1940 to the 1st and 6th Armoured Division, the 1st had lost most of their equipment in the Battle of France and the 6th was a newly formed unit. While these units were sent to North Africa, the defects in the engine cooling system forced the Tetrarchs to stay behind, until they were taken out of armoured divisions due to the "light tank" concept becoming obsolete, most of the '''Tetrarchs''' were shipped overseas and the Soviet Union compared their role to that of the T-70 light tank, they were mainly used for reconnaissance and for airborne operations.

 It was introduced in [[Update 1.55 "Royal Armour"]] along with the initial British ground tree. A light tank with a [[Ordnance QF 2-pounder (40 mm)|2-pounder]], it fits the British light line of a fast tank with a powerful gun but weak armour. The Tetrarch plays like any other Rank I vehicle in the game. Zip around with high speed to the destination and get a first shot off on the enemy tank (preferably the gunner). The 2-pounder can penetrate most enemy tanks at close range and the 40 mm shells can cause a decent amount of shrapnel that can damage most of the internals at the area of the penetration. The mobility is great with the adequate horsepower to propel the 7 ton tank around. The armour is barely adequate for Rank I, with its flat surfaces encouraging penetration with the cramped interiors making one-hit destruction a worrying situation for the Tetrarch.

The fast rate of fire is also helpful to pinpoint their crew members one by one.
 * [[M3 Stuart (Family)|M3]]/[[M5 Stuart (Family)|M5]]: the Stuart series light tank have equally fast top speed both on road and off road, meaning they can rush a cap point or relocate just as swiftly as you can. They also have way faster turret traverse, allowing them to deal with close quarter combat much more efficiently, making them deadlier. Although their gun calibre is smaller at 37 mm, they can still cripple or knock you out with a single shot due to your cramped crew. They have a bouncy upper hull glacis and a sturdy gun mantlet, so avoid shooting there. Your APHE shell can frontally penetrate and cripple or knock them out in return. Try using your stabiliser to shoot first.
 * [[AS 42]]: this is a small and fast Italian SPAA car armed with a 20 mm autocannon. The gun has no problem piercing your thin armour from any angle, and the fast rate of fire means that it can quickly wipe out all your crew. Since it is small and fast, it can be challenging to target it given the Tetrarch I's extremely poor turret rotation. Rotate the hull to aim faster, and spray MG bullets towards it between reloads.

 * [[Ka-Chi]]: this amphibious Japanese tank can be quite strong. It has 50 mm frontal armour which can defeat most of the Tetrarch I's rounds when at a distance and/or angling. It also has spaced armour on the hull sides, and most noticeably the additional floaters at the hull front and back. The floaters will act as very effective spaced armour, absorbing HEAT, HE and even kinetic rounds. The Ka-Chi has 7 crew spread out inside, meaning it is pretty impossible to one-shot it using APHE. It is not advised to engage it from a distance, since the hull is quite thick especially with the floaters. To avoid the large hull and target the weaker turret it is best to get close, preferably within 400 m. The Tetrarch I's APHE can easily take out the Ka-Chi's turret crew. Only shoot when it is distracted or reloading though, as its 47 mm APHE can undoubtedly penetrate and knock out all 3 crew members in the Tetrarch at any range and angle.

 Use the Tetrarch's awesome off-road mobility and climbing to get into an unusual position behind enemy lines, fire a few shot and disappear in the shadows. If the Tetrarch gets spotted before finishing an enemy, flee: staying alive is more important than destroying someone, finish the enemy off later, when they have forgotten about the Tetrarch's presence.
-Otherwise, anyone playing the Tetrarch should get back behind friendly lines if two or more enemies are approaching since it's cannon can only take down enemies one by one, patiently shooting down each crewman.

-Development for this tank started in 1937 by Vickers-Armstrongs privately as the '''Light Tank Mk VII''' and nicknamed the ''Purdah''.<ref name="ImagesOfWarBritishWW2Tanks">Pat Ware. ''Images Of War: British Tank: The Second World War'' Great Britain: Pen & Sword Military, 2011</ref>. The intention was for the tank to be sold to either the British Army or foreign countries as the latest light tank of the company. It's predecessor, the ''Mk VIB Light Tank'', was considered insufficient in firepower, armed with only machine guns. The new design would use the new 2-pounder gun along with a coaxial machine gun. The Mk VII design was finished around 1938, and the British War Office (government administrating the British Army) took up the design for trials in May 1938 that lasted until June. The trials tested the Mk VII's ability to act as a "light cruiser", but this failed as the [[A13 Mk I|A13 cruiser]] was much better at the task. Thus, it was suggested that the Mk VII be tested as a light tank instead and production to be started for the trials. During the trials, the War Office gave the Mk VII the specification number '''A17''' for identification and was put into limited production in November 1938 with a few design changes. It was initially known as the "Purdah" from its standardization date, but in September 22, 1941, the Mk VII Light Tank also received the name '<nowiki/>'''Tetrarch'''' as part of an order to distinguish tanks by chosen names.

 Demand for the tank fluctuated depending on the War Office demand for the tank. In July 1938, the first order came for 70 tanks, then 100, then 120 in November, then back to 70 in July 1940. This order then jumped back to 100, then finally settled on 220 after Metropolitan Cammell Carriage and Wagon, a part of Vickers-Armstrong, had enough armour plating to create that many tanks. Production was suppose to start in July 1940, but was delayed due to many factors, especially with World War II now on full swing against Germany. Light tank also soon fell out of War Office use after the poor performance they showed in the Battle of France, so military production was focused on the infantry and cruiser tanks rather than light tanks. Bombing raids by the Luftwaffe in the Blitz also disrupted the production of the tanks when the factories intended for their production were targeted. These delays due to waning military interest, the pressure of war, and enemy attacks caused only a small number of Tetrarch light tanks to be produced, with 177 units produced from 1938 to 1942.<ref name="ImagesOfWarBritishWW2Tanks" />
