Development of the SPG started in the second half of 1941. The prototype underwent trials on February 12, 1942 and saw service in July 1942. The Pressed Steel Car Company produced 100 vehicles. Baldwin Locomotive Works modified the SPGs and re-equipped some M30 carriers. The vehicle saw service in the field artillery battalions and was used by the U.S.A. forces in Western Europe.
This SPG gains increased alpha and a very fast shell travel time compared to the M44 but it has a narrower gun traverse and slower reload and aim time. As is par for the American SPGs it has a slow hull traverse speed, but a respectable top speed and acceleration.
The M12 leads to the M40/M43.

Pros and Cons
- Gun range: stock: 1350 m, top: 1400 m
- Decent damage for a tier 7 artillery
- Decent accuracy and gun arc
- Best aim time for its tier
- Horrible traverse speed
- Low vertical shell arc
- Can only hold 20 shells, likely to run out of any shell types before end of game
This tank is quite a change from the M44. The reload and aim time are much slower and due to the narrow gun traverse you will be forced to move the hull more often than you would like. Considered a lackluster artillery piece before the nerf of 8.6, the M12 received further nerfs. Considered one of the worst artillery pieces in a tier full of bad artillery pieces, the M12 does not have much going for it. It is merely average in most important stats: Average accuracy, average damage, average reload, average mobility. It's only real advantage is its decent horizontal gun arc, but this is surpassed by the G.W. Panther and the Lorraine 155 50. However, it is worth noting that it has the best aiming time in its tier, making it truly shine when it can dedicate to counter-battery enemy artillery.

- Install Engine researched by T40 or M3 Lee
- Research suspension first

The 155 mm Gun Motor Carriage M12 was a U.S. self-propelled gun developed during the Second World War. Only 100 were built; 60 in 1942 and a further 40 in 1943. It mounted a 155 mm gun M1917, M1917A1, or M1918 M1, depending upon availability: a weapon derived from the nearly identical French 155 mm GPF gun of World War I vintage. The M12 was built on the chassis of the M3 Lee tank (some sources claim that later M12 used the M4 Sherman chassis, but this might be a confusion with the M12's use of "Sherman-style" bogie trucks with trailing idlers). It had an armored driver's compartment, but the gun crew were located in an open topped area at the back of the vehicle. An earth spade (similar to a bulldozer blade) at the rear was employed to absorb recoil. This layout, a large gun mounted in an open mount at the rear with a spade, was the pattern adopted for many years by other heavy self-propelled artillery. This tank was also used to destroy small fortifications and pill boxes, and it was highly successful.
During 1943, the vehicles were used for training or put into storage. Before the invasion of France, 74 M12s were upgraded in preparation for combat operations. They were employed successfully throughout the campaign in NW-Europe. Although designed primarily for indirect fire, during assaults on heavy fortifications, the M12s were sometimes employed in a direct-fire role.
Limited storage space meant that only 10 projectiles and propellant charges could be carried on the vehicle. Given this, a similar vehicle, but without the gun, was produced as the Cargo Carrier M30. This was designed to transport the gun crew and additional ammunition. In operational conditions, the M12 and M30 would serve in pairs. The M30 was armed with a .50-caliber Browning M2 machine gun. It could carry 40 rounds of 155 mm ammunition.The sole surviving M12 GMC is displayed at the Fort Sill museum . It was stored at the United States Army Ordnance Museum in Aberdeen, Maryland, USA, before being transferred to Fort Sill in November 2010.
