3 Medium Regiment (India)

3 Medium Regiment is part of the Regiment of Artillery of the Indian Army.

Formation
3 Medium Regiment was raised on 14 May 1956 as a field artillery regiment at Delhi Cantonment. The regiment was formed out of 50, 52, 53 and 54 artillery post groups, which were reorganised to form the present batteries. The Post Group organisation ceased to exist thereafter.

Lieutenant Colonel (later Lieutenant General) J. F. R. Jacob was the first commanding officer. The class composition was initially planned to be 'all-India', but then it was decided to be a 'Single Class' regiment composed entirely of Sikh gunners.

Operations
The regiment under the command of Lieutenant Colonel (later Major General) LS Lehl, VrC took part in the liberation of Goa, but didn't see much action as the Portuguese offered hardly any resistance. In 1962, the unit was deployed in Sikkim, but this sector did not see any action.
