The Indian Armed Forces fought two wars between 1962 and 1965 from which valuable lessons were learnt. It was realised that the age-old arms and ammunition which was till then used were no longer tenable. Keeping pace with the advancements in technology, the government initiated a modernisation process in the services. Funds were allocated for acquiring new tanks, guns, aircraft and ships to augment the strike potential of the services.

The Corps of Signals, which was responsible to provide operation communications mainly to the formations of Indian Army and, to a limited extent, to Navy and Air Force, also took stock of the emerging technological revolution and evolved new communication strategies to meet the command and control requirements of the field commanders. The Ministry of Defence formulated and implemented its modernisation plans and Corps of Signals got a fair share of the financial provisions made in the five year Army Plans. These were fully utilised for making the state-of-the-art equipment so that the Signal units could wear a new look. During 1965-1971, efforts were made to develop better radio sets, telephones, cables and special vehicles which could carry the communication equipment to the battlefield with matching mobility and readiness. The Signal personnel were trained hard to handle the new equipment and the on-the-job training conducted by the units became result-oriented. The efforts put in during these six years bore fruit when the Indian Armed Forces took on their adversary in 1971. They were ready for a war which was intense and fought on many fronts and over diverse terrains. The Corps of Signals personnel were earnestly involved in the war and used their newly acquired skills and equipment to the hilt.
