Description
The Medium Tank M2 is a rank I American medium tank
with a battle rating of 1.3 (AB/RB/SB). It was one of the first American tanks to be released with the American ground tree in Update 1.45 "Steel Generals".
The M2 medium tank, as the first medium tank of the American line-up, has some features that would become staple of the American ground forces that would be great to be familiarized with. The first of which is sloping front armour which, despite the base thickness of only 28.5 mm, gives the total frontal effective armour of 40 mm. The second is the handling and mobility, which are quite comparable to its successors with its weight distribution and speed. As such, driving experience with the M2 would greatly benefit in later games once past Rank I.
The M2 Medium has the most machine guns on a tank in the game. There are nine visible machine guns, two on the turret, four in the hull sponsons, two fixed in the front hull, and the coaxial machine gun. The reason for the M2 Medium's many machine guns is due to the US Army's infantry inter-war belief in the machine gun being the main weapon to support an assault, with the 37 mm gun only meant to support the tank when facing other tanks. The priority in the machine gun can be seen with the metal flaps on the rear, which would show in-game in the armour viewer as 5 mm RHA plates. These plates were meant for the rear sponson gunners to shoot the machine gun rounds to "ricochet" the bullets downwards onto trenches as the M2 Medium crosses over them. While it isn't possible to do this in the game, it is a good indication on how important the machine guns were in the M2 Medium's design.
General info
Survivability and armour
Armour type:
- Rolled homogeneous armour
- Cast homogeneous armour (Gun mantlet)
Armour | Front (Slope angle) | Sides | Rear | Roof |
---|---|---|---|---|
Hull | 28.5 mm (53°) Front glacis 28.5 mm (17-48°) Lower glacis 28.5 mm (13-16°) Driver's port |
25.4 mm (16-36°) Front 25.4 mm Everywhere else |
25.4 mm (1°) Hull top 25.4 mm Top engine deck 9.5 mm (12-52°) Bottom engine deck |
9.5 mm |
Turret | 25.4 mm (10-14°) Turret front 25.4 mm (9-54°) Gun mantlet |
25.4 mm (20°) | 25.4 mm (19°) | 9.5 mm |
An anti-tank weapon greater than 37 mm can often find a way through the armor. One significant weak point on the frontal glacis would be the driver's hatch, as it is lightly sloped at about 15°. Not only that, but getting hit in this location would often lead to a knock-out of both the driver and commander in the center, which would incapacitate the M2's mobility and firepower.
Though the M2 Medium seem to be cramped for six crew members, they are actual quite spaced from each other so regular AP shots would have to precisely hit each mark in a line to knock them all out. However, if an adequate APHE round penetrates from the front or side, it could incapacitate the majority of the crew in one shot. A hit between the rear 2nd and 3rd bogie suspension at the hull sides as the ammunition is stored there and a shot in this region could either remove the majority of the ammunition or blow the tank up with a rack detonation.

Usage in battles
The M2 with its decent frontal armour, mobility, and firepower allows it to compete in Rank I. However, it is best to use the vehicle from a distance as it would increase the sloped armour effectiveness against enemy rounds, which would've lost most of its power due to the distance. While the 37 mm cannon can penetrate most tanks at the BR, the gun is on a slow traversing turret, requiring for careful alignment of the turret in the right direction. Flanking enemies would make this a problem so stay in an area that can narrow down enemy paths and stay alert.
Past that, the M2 can prove forgiving with its aforementioned sloped armour and large crew size of six. Though a penetrating shell could knock out a good number of the crew in the cramped interiors, it will prove unlikely to knock out every single crew member in one shot. As such, even if shot on the side, it is possible to react against the flanking enemy if the driver or commander is still alive to align the gun onto the offending target.
In short, the M2 is a good jack-of-all-trades vehicle for the American tree line, a common trait as one moves on into the Rank II and Rank III vehicles

Pros and cons
Pros:
- Reliable 37 mm gun with good penetration and rate of fire
- Has a higher than average crew count of 6 crew members
- Has 7 machine guns modeled and functional, which can be effective against thin-skinned vehicles and aircraft
Cons:
- Cramped tank interior and large number of crew means a penetrating hit will more than likely get one
- Turret rotation is very slow
- No ammunition with HE filler
- Large and tall, making it an easy target
- All the ammo are packed into neat little boxes in the bottom of hull, a shot at suspension area could set one off
- 7 machine guns is of questionable value against all but the lightest armoured vehicles
- Very thin roof armour of 9.5 mm
- Past the front, the overall tank surface is poorly sloped and angled
- Tall center of gravity, resulting in very unstable turns at high speeds and at risk of tipping
History
Development
The development of the M2 light tank also started a development for a new medium tank. Rock Island Arsenal took up the project and developed a vehicle known as T5. It was basically an upscaled M2 Light Tank, still using the vertical volute spring suspension (VVSS), and this modified vehicle was designated the M2 Medium Tank in June 1939. 18 units in, and the tank was upgraded with a redesigned turret and a more powerful engine, this variant was designated the M2A1 Medium Tank.
The M2 Medium Tank had a high profile, with a height of 9 ft. 3 in., and had lots of machine guns on it (nine machine guns!). On each corner of the hull had a mounted machine gun, each with a crew member to man it. In the front, the driver can fire two fixed machine guns facing forward on the glacis plate. Two machine guns could be mounted on the turret as anti-aircraft weapons. The turret mounted a 37 mm M3 gun with a coaxial machine gun. The tank had a crew of six, commander, driver, and the four machine gunners.
Production
1,000 of these tanks were ordered by the government in 1940 to be manufactured by Chrysler, but the German success in the Battle of France showed that the M2 Medium was becoming an obsolete design, so the order was changed to instead produce 1,000 M3 Lees before the M2 even started production. In this period, Rock Island Arsenal produced 94 M2A1 medium tank until August 1941. This brings the total produced tank to 112 M2 medium tanks, 18 M2s and 94 M2A1s. These M2 tanks were used for training at states for tank crew members.
Despite its obsolete status by 1940 due to the Soviet T-34 tanks and the German Panzer III tanks, it provided useful insight in the future of American medium tank designs. The M2 was one of the first American designs to incorporate sloping armour on the glacis effectively, and revealed to the American generals that an excessive amount of machine guns on tanks were useless in battle.
In-game description
American builders moved away from combination wheel and track vehicles to develop a new tank they termed the T5. In an attempt to save time and money, while also standardizing construction, they pulled components and units from the prototype T2 light tank (the prototype for the mass-produced M1) in addition to its layout and some chassis elements. The Rock Island Arsenal headed up the design process for the T5, which began in 1936, though the first prototype was ready for trials at the Aberdeen Proving Ground in February 1938. The experience showed that the powertrain could not cope with combat weight exceeding 15 tons and that the tank's frontal bullet-proof armor needed an upgrade. A slanted armor plate soon appeared, protecting the crew from all bullet calibers and shells up to 37-40 mm at long distances.
Later the T5 Phase II modification and its alternative powertrain appeared, and in spring of 1939 the engine was replaced with the 350 hp radial Wright R973. Other upgrades included installing the frontal hull plates at a better angle and moving a pair of machine guns to the right-hand side. The new vehicle was termed the T5 Phase III.
The T5E1 prototype and its Guiberson diesel engine was modeled after the T5. It was later employed in trials for experimental equipment and twin-mounted 37 mm cannons.
The tank headed for full-scale production and was accepted by the American army under the designation M2. The first set of 15 units got under way in August 1939 at the Rock Island Arsenal, with 18 total units featuring that particular modification eventually built.
The tank's primary drawbacks were weak armor, a riveted construction, a high profile, narrow tracks, and an under-powered engine.
