About OTA Chennai

The history of OTA dates back to World War II, when seven Officer Training institutes established in India. However, these schools were closed down after the war. In 1962 after the war with China, India felt the need to establish Institutes to train more officers for Indian Army, two officers training schools were established as a result, one in Chennai (then Madras) and one in Pune. These Officer Training Schools (OTS) were established with the motive to cater officers for the emergency commission.

The first Emergency Commission (EC) course began with a complement of 442 young Indians. Their training began in this prestigious institution on 15 Jan 1963. Brig Ram Singh the first Commandant along with Shri C Subramaniam, the then Union Minister for Steel and Heavy Industries, formally inaugurated it with an inspiring speech that has proved prophetic time and again.

The Emergency Commission courses continued till April 1965 and EC–12 was the last course to pass out. When the Emergency Commission Courses were discontinued, OTS started training Gentlemen Cadets for Short Service Commission (SSC).

The scheme also included SSC Course (compulsory liability scheme) for Class I and II Gazetted Officers of the Central Government and Public Undertakings. The scheme ended in 1968 when SSC courses for Technical Arms and Services were introduced.

In the seventies few essential infrastructural developments like Swimming Pool, Auditorium, Science Block and Laboratories, Drill Square, Cadets Mess; Weapon Training sheds were created to facilitate GC’s training.
