The 155 mm M1 cannon was one of the best artillery weapons of its class in the world, as evidenced by the fact that it remained in service long after WWII. It was known as the Long Tom and its design managed to balance high accuracy, range and projectile effect with the mobility of the entire weapon. It was produced in several slightly different versions, the M1, M1A1 and the M2 with a different recoil spring. It was usually moved behind tracked tractor-trailers, and only rarely behind a 21/2 ton GMC automobile.
The weapon served with a total of 30 artillery battalions (as of 8 May 1945). These were the following units :
190th, 200th, 240th, 244th, 261st, 273rd, 514th, 515th, 516th, 528th, 540th, 541st, 546th, 547th, 548th, 549th, 559th, 561st, 634th, 635th, 731st, 733rd, 734th, 976th, 977th, 978th, 979th, 980th, 981st. and 989th artillery battalion
