This page is about the American cannon M1A2 (37 mm). For other uses, see M1 (Disambiguation).


Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.




The United State Army first developed an interest in 37 mm anti-aircraft artillery in World War I. However, despite requesting a design from legendary designer John Moses Browning, the Army did not adopt it. In the 1930s, the interest in a 37 mm gun reappeared due to the Coast Artillery Corps only having .50 M2HB Browning machine guns for anti-aircraft use. Needing a new automatic weapon that would handle intermediate air defense, the 37 mm gun was revisited and with new fire control devices, the design was adopted as the 37 mm M1 in 1939. The M1A2 version is a towed variant of the gun meant to serve as the Army's anti-aircraft gun of choice. However, soon after, the 40 mm Bofors L/60 was adopted under license and began to supplant the M1A2 in the Army's anti-aircraft role. While it was still used as a towed AA weapon in the Pacific Theatre and remained during the war as a coastal defense weapon, it was replaced by the Bofors by 1942. As a result, the old M1A2s were fitted to the M3 Half-Track along M2 Brownings, to create the M15 CGMC in order to both keep the gun in service, and increase the firepower of the Army's SPAA vehicles. The M1 would also have another variant, the M9 (37 mm), used on PT boats during World War II.


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