Advanced medium tank with increased health that is very effective against infantry, vehicles, and structures. Turret weapon is effective against vehicles and can damage tanks. Primary cannon must face targets directly to fire.

The M3 Grant Medium Tank is a medium UKF tank. In skirmishes it is available from the , though it requires an additional research upgrade in order to unlock its production from the structure.

The Grant fulfills an interesting hybrid role compared to the other UKF tanks. It is significantly slower than the , but faster than the . Conversely, it is more durable than the Crusader but not nearly as durable as the Matilda, having significantly lower armour values but impressive amount of health.

Its offensive armaments is where the M3 Grant really highlights its difference. This unit actually has two tank cannons. The rotating turret cannon is similar to the 's weapon, although with slightly better penetration. Like the Stuart, this 37mm cannon is effective against infantry and light vehicles. The second cannon is a stronger weapon intended for anti-tank duties. It is frontally mounted and can only fire in front of the Stuart. This 75mm cannon packs a much stronger punch with greater damage and penetration compared to its other weapon.

Upon reaching veterancy level 1 it gains the active ability Steady Assault, which significantly increases rate of fire at the cost of mobility.

With two cannons, the M3 Grant is a potent tank. So long as it can bring both cannons to bear, it offers a lot of firepower. While technically not an anti-infantry unit, the doubled firepower can make it surprisingly effective against infantry. As for vehicles, both cannons combined allow it to deal with light vehicles very effectively. Against more armoured targets, the 37mm cannon may struggle with penetration, but the larger 75mm cannon will reliably penetrate most tanks at range, such as the . Regardless, the two cannons combined make the M3 Grant a more effective anti-tank unit compared to the other UKF tanks.

The Grant is powerful when it can keep facing its opponents, but this can easily be circumvented if the tank is flanked. As its mobility and durability stands in the middle ground between the and the , it should be treated as a jack of all trades unit with a bonus to anti-tank over anti-infantry compared to the other two tanks.

This unit benefits from the Armored Vehicle Training upgrade available at the .

Veterancy Abilities

  • Steady Assault: Active ability granted upon reaching veterancy level 1. A timed ability that when activated, temporarily increases the Grant's rate of fire but reduces its mobility greatly by decreasing speed and rotation rate. So long as the mobility is not required, it can be a fantastic offensive boost. If used poorly though, the lack of mobility can leave the Grant vulnerable.

Research Upgrades

  • Armored Vehicle Training: Available from the Training Center. Grants +1250 veterancy XP, and veteran medium/heavy vehicle units gain +10% accuracy, +10% reload speed, and +10% penetration.


  • The M3 Grant has two cannons:

    • The smaller 37mm cannon located on the rotating turret is similar to the same weapon used by the , although this weapon has slightly better penetration. Effective against infantry and light vehicles.

    • The larger 75mm cannon is located on the front hull and can only fire in a frontal arc. This is its dedicated anti-tank weapon, featuring far more damage and penetration than the smaller cannon.


  • The official name is the M3 Medum Tank, or M3 Lee. It was an American medium tank produced in 1941-1942. The 'Grant' name was given to tanks that used the British pattern.

  • The tank has a very unique and odd design as one can see immediately. This was created out of an immediate need for an American medium tank armed with a 75mm weapon, while also supporting the United Kingdom's demand for thousands of medium tanks at the time.

    • The design was thus a compromise, meant only to serve until they could be replaced by the now widely known M4 Sherman tanks.

  • While the M3 had good firepower, armour, and mobility at the time, it also harboured some serious disadvantages. These included riveted construction, high silhouette, and the poor sponson design that limited the 75mm cannon's arc of fire as well as preventing hull-down position.

  • The Soviet Union received nearly a thousand M3 tanks over the course of 1941-1943. However, by the time they received them the superior T-34 tank was already widely available to Soviet forces. This resulted in soldiers commenting that the M3 was "Братская могила на шестерых", which literally translates to "Brotherly grave for six".

Change Log

1.6.5 May 1 2024

Requsition Grant Unlock

We want to maintain the Grant’s role as a very powerful tank once it has been unlocked that is more in line as a tier 4.5 tank, but it still comes too early, outcompeting other options even with the current costs.    

  • Fuel cost increased from 35 to 50 

1.6 'Coral Viper' April 2 2024

  • The cost of the M3 Grant Unlock upgrade is being increased. The Grant has proven to be a very powerful unit, and we want players to have to invest a bit more to unlock it.  

    • Cost increased from 125 manpower and 25 fuel to 125 manpower and 35 fuel.
