M102

The M102 was developed as a lighter 105 mm howitzer to replace older M101-series weapons in many U.S. Army roles. U.S. Army Rock Island Arsenal material identifies the XM102 as the experimental version of the M102, and the Army Historical Foundation describes the production weapon's lightweight construction and service history. The towed-howitzer category is appropriate.

M102's value was portability. It could support airborne and light forces that needed artillery fire but could not carry heavier guns. Its circular firing platform, low weight, and 105 mm ammunition made it suitable for Vietnam-era firebases and later use, including AC-130 gunship installations in modified form.

The howitzer offered responsive indirect fire at lower logistical cost than heavier systems. Its limitations were range and shell weight compared with 155 mm guns, leading to eventual replacement by M119-series howitzers in many U.S. units. It remains important as a Cold War and Vietnam-era light artillery system.
