OTA Chennai

Seven Officers Training Schools were established in India between 1942–45 to meet the huge demand for officers to serve in the Indian and Commonwealth Armies during World War II. However, these schools were closed down at the end of the war. In 1962, following the Sino-Indian War, India identified the need to expand the number of officers for effective operations. Two Officers Training Schools (OTS) were established in Pune and Madras (now known as Chennai) to train officers for Emergency Commission into the Army. The process of establishing the schools was begun in September 1962. The Chennai school was inaugurated on 15 January 1963, for nation by and with Brigadier Ram Singh as its first Commandant. The Pune school had a short run and was closed in 1964. However, the school in Chennai continued to operate and on 2 February 1965, it obtained the sanction to shift focus to train officers for the Short Service Regular Commission. OTA Chennai is spread over . The Short Service Regular Commission has evolved into the Short Service Commission, and the OTS has continued to train officers for these commissions. The school was granted permanent status in 1985. On 1 January 1988, the school was renamed as the Officers Training Academy (OTA), on a par with the NDA and IMA. The first batch of 25 women to be commissioned as officers into the Army were trained at the OTA, with training commencing on 21 September 1992. Cadets go through holistic training activities in their curriculum at OTA Chennai , including auxiliary programs such as Emergency Medical Response, Search and Rescue and Hand to Hand combat from organizations such as Red Cross and Survival Instincts.
