General info

Survivability and 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.

Mobility

Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forwards and backwards.

Usage in battles

Even though it is a medium tank, its armour is very similar to the Leopard 1. The mantlet can bounce or soak some APDS/APFSDS shells but it will usually end up damaging the cannon breech and knocking out 1 or 2 crew members. The best tactic is to flank using your speed or snipe using the laser rangefinder for precision shots.

III	Filters		Crew Replenishment	Elevation Mechanism	M416	Smoke grenade
IV	Transmission	Engine		Artillery Support	M456	Laser rangefinder

Pros and cons

Pros:

• Good main gun handling; quick rotation and gun lifting
• Has a laser rangefinder, making sniping much easier
• Spaced armour in the turret allows taking some autocannon hits, the mantlet are immune to HESH, and some AP shots bounce if the turret is angled
• Quick and agile tank when upgraded

Cons:

• No stabilizer
• Vehicle grind is tedious with only the stock APDS ammunition before upgrades
• Turret, while more armoured than its German cousin Leopard 1, is quite boxy and can be spotted easily if peeking over a ridgeline or hilltop
• Only 19+1 rounds in its ready racks, any more ammo is stored next to the driver in the lightly armoured hull and can be easily set off by a penetrating hit

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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.
