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

Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they can be substituted with softer forms such as "inadequate" and "effective".




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 If the historical reference turns out to be too big, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: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 devblog entry (if applicable) and the ingame encyclopedia description (under === Encyclopedia Info ===, also if applicable).

In-game description

"The M2 series traced its family tree back to the experimental T2s, with the M2A4 ending up the largest and most successful modification. Development began in 1939 after running trials for light tanks designed for infantry support as well as the M1 series. The M2 infantry tank was used as the base for construction, a model that was to undergo significant modification. The turret armor as well as the front end were thickened to 25 mm, capable of withstanding hits by light cannons and high-caliber machine guns. The tank's weaponry was also improved with the installation of an M5 37 mm cannon paired with a 7.62 mm machine gun in the single turret.

Another 7.62 mm machine gun was mounted in the front hull plate, with two more on the sides. An antiaircraft machine gun could be mounted on the top of the turret, and additional viewing slits were cut out of the turret and cupola. Most tanks featured the 360 hp Continental W-670-9A engine, which pushed their top speed to 56 km/h. Several tanks in the series were equipped with Guiberson T1020 diesel engines.

Given that September 1939 saw a spike in orders, the Rock Island Arsenal was no longer able to keep up on its own with the demand being placed on it by the US army. A tender for an additional batch was announced and won by American Car & Foundry. In October 1939 a contract for 329 tanks was signed, though it was soon expanded to 365. The last ten were assembled in April 1941 by Baldwin Locomotive Works, meaning that 375 M2A4s were produced in 1940.

The tanks only saw action on Guadalcanal and other Pacific islands. A few others were shipped to the UK via Lend-Lease and used there to train M3 medium tank crews."


Excellent additions to the article would be video guides, screenshots from the game, and photos.
