51 Medium Regiment is part of the Regiment of Artillery of the Indian Army.
The regiment was raised on 1 March 1961 in a field area at Harchura in Assam as 51 Mountain Composite Regiment (Pack). It was one of the few animal pack artillery units raised prior to the 1962 war, when the gravity of the threat posed by the Chinese started emerging. The first commanding officer was Lieutenant Colonel (later Brigadier) Anyattuparmbil John Itty Cheria. The regiment had a headquarters battery, three mountain (pack) batteries with 3.7 inch mountain howitzers and a mortar battery equipped with 120 mm mortars. Three batteries were of Dogra troops and one of Sikhs.[1] [2] The regiment shed its pack animals in 1966.[3] After 25 years as a mountain regiment, the unit was converted to a field regiment and is currently a medium regiment. The regiment presently consists of 139, 140 and 141 medium batteries. Of the initial four batteries, 142 Mountain Battery was hived off and formed the nucleus of 182 Light Regiment (Pack) in September 1965 (presently 1821 Light Regiment).[4]
