It entered service in the ‘60s but thanks to the improvements made in 1977 on the M-110 A1 version, it acquired improved operational efficiency. The M-110 A1 was armed with the new 203 mm long range M201 gun able to use a wide range of ammunitions. The project was characterized by an excellent mix in terms of firepower and mobility thanks to its reliable chassis (the same of the M-107). The M-110 A1 was deployed in the division artillery to perform tasks as general support, counter-battery fire and suppression of enemy positions. It was widely used during the conflict in Lebanon and during the first Gulf war.
