Description
The Ratel 90 is a rank IV British light tank with a battle rating of 6.3 (AB/RB/SB). It was introduced in Update "Ixwa Strike".
The Ratel 90 is an IFV designed to provide fire support for the Mechanized South African Battalions in combat. It was modified to this duty with the identical turret found on the Eland 90 Mk.7.
With a needed playstyle keen to recon and opportunistic target eliminations by flanking, the Ratel 90 is currently the fastest vehicle available for the British tree at the rank.
Unfortunately, the vehicle is fast not because of a good engine, but instead because of the cutback of any armour. Players accustomed to holding off some shells in similar ranked vehicles as the Tortoise will have troubles surviving in this IFV. So instead it shall be played similarly to the Charioteer, now with more cooperative abilities as the scouting.

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
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- Great penetration and adequate ballistics; currently the first accessible vehicle in the British ranks with HEAT rounds
- Adequate mobility once fully upgraded (on roads and optimal terrains)
- Scouting, smoke grenades and smoke shells provide great supporting abilities
- Large vehicle size helps with the 90 mm gun recoil
Cons:
- Gun is not stabilized, the vehicle needs to stop to fire accurately; HEAT requires a very precise firing
- Huge size, hard to conceal and difficult to manoeuvre in close quarters
- Very unreliable armour and only 3 crew members; easily destroyed on all angles even with 12.7 mm MG
- Despite good top-speed, acceleration is not great on rough terrain; low power-to-weight ratio (14 HP/t)
- Wheeled configuration and underpowered engine struggles on deep sand and snow
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: 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></ref>, as well as adding them at the end of the article with <references />. 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.
