Developed in 1945 on the basis of the M24, with a total of 150 vehicles manufactured. The tank was never used in combat during World War II, but it did see action during the Korean War.
While the hull is a conversion of the M24 Chaffee, unfortunately the extra weight means it retains little of the original vehicle's maneuverability. The initial acceleration and hull traverse rate are very poor and the suspension should be the first upgrade since it can't mount the upgraded gun without increasing the weight limit. Upgrading the gun will allow you to fire almost across the map (the increased range isn't listed on the in-game stats). Despite the vehicle's flaws, both 105mm guns hit very hard for their tier and allow the M37 to punch above its weight in heavier battles. Another important thing to note is the M37's extremely wide gun traverse arc of 52 degrees, which, along with the GW Panther, gives it the widest gun traverse arc in the game for an SPG without a traversable turret.
As of the 8.6 update the M37 has been bumped up to tier 4, with the previously tier 4 M7 Priest taking its place.
The M37 leads to the M41.
Pros and Cons
- Excellent ammo capacity
- High top speed
- Good firing range with the top gun.
- Excellent signal range
- Widest gun traverse arc for a non-turreted SPG in the game
- Surprisingly good gun depression
- Slow traverse speed
- Tiny splash damage radius
- Rather poor accuracy, but on par for its tier
- Somewhat large target, hard to camouflage and easy to hit
The M37 has moved up a tier, being the M7's historical successor. Mounting similar guns as the M7 Priest a tier below, the M37 shoots much faster than the M7 Priest with ridiculous amounts of ammunition. By not needing to get so close to the action, the minimal armor becomes far less of an issue. This Artillery has the same damage, penetration and firing range as the Wespe and Lorraine39 L AM, but it carries far more ammunition and has a much wider gun arc, making it superior in this aspect. The massive ammo supply allows liberal use of guess work when firing at unseen targets, a definite advantage over the limited ammo capacity of other SPGs. With that said, the M37 is arguably the best of the normal tier IV artillery pieces. The Birch Gun has a much faster firing gun with far less damage and a fully traversable turret, and the Sturmpanzer II lobs larger, heavier, more powerful shells at a higher ammo cost, worse accuracy and worse rate of fire.
Being based on the M24 Chaffee's chassis, the M37 is reasonably fast, although the removal of its top engines hampers its acceleration.
- The SCR 506 radio carries over from the M7 Priest. If you have it researched, you can install it immediately.
- Research the upgraded suspension first for added traverse speed and weight capacity.
- Next you can research the 105 mm Howitzer M4 for improved RoF, accuracy, and much-improved range.
- Go from there.
The 105mm HMC M37 was based on a lengthened chassis of the M24 Chaffee light tank, and the vehicle was modified much the same way as the 105mm HMC M7, which used the medium tank M3 or M4 chassis. The M4 105mm howitzer was the same as that used in the howitzer-armed Shermans, and was mounted on the M37 to the right of the carriage's centerline, replacing the assistant driver's position. The .50cal machine gun ring mount was to the right of the howitzer mount.
