Integrated Theatre Commands of the Indian Armed Forces are varying degrees of synergy and cross–service cooperation between the military wings of the Indian Armed Forces. Following Independence, in 1949 a joint educational framework was set up starting with the first tri-service academy in the world, the National Defence Academy, and over the years this joint educational framework has been expanded to bring officers from the different services together at different stages of their careers.
