== Description ==

The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} British medium tank {{Battle-rating}}. It was introduced during [[Update "Winged Lions"]] as a reward for the [[wt:en/news/7469-event-operation-w-i-n-t-e-r-en|2021 Operation W.I.N.T.E.R.]] event.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.''

== Usage in battles ==

''In general is the A C I very good at head on engagements, due to its for its BR very well armored front. The sides are with a thickness of only around 45 mm relatively good penetrable at 2.7. Tanks that use HE-Shells are dangerous, because the explosive doesnt take the sloped armor into account and will often take out the driver and the machine-gunner as well as the transmission. The lower front is quite vulnurable, if shot, the transmission will most likely break down, the crew won't take damage usually.''

=== Pros and cons ===


'''Pros:'''

* Diversely sloped frontal hull armor is sturdy against common foes, like [[M3 Stuart (Family)|M3A3 Stuart]] and [[M5 Stuart (Family)|M5 Stuart]], [[T-50]]
* Outstanding gun depression, allowing hull-down tactics
* Can easily frontally engage most enemies
* Fast reload allows quick follow-up shots

'''Cons:'''

* Only 44 mm of side armour
* Painfully slow reverse speed of -4 km/h
* Tightly packed crew
* Frontal turret armour is quite weak
* Slow acceleration

== History ==

''Describe the history of the creation and combat usage of the 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Vehicle-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under <code><nowiki>=== In-game description ===</nowiki></code>, also if applicable).''
