The Indian Army numbers over 1.1 million strong and fields 34 divisions. Its primary task is to safeguard the territorial integrity of the country against external threats. The Army has been heavily committed in the recent past to counterterrorism operations in Jammu and Kashmir, as well as the in the Northeast. Its current modernization program focuses on obtaining equipment to be used in combating terror. The Army often provides aid to civil authorities and assists the government in organizing relief operations.

         The Indian Navy is by far the most capable navy in the region. The Navy's primary missions are the defense of India and of India's vital sea lines of communication. India relies on the sea for 90% of its oil and natural gas and over 90% of its foreign trade. The Navy currently operates one aircraft carrier with two on order, 14 submarines, and 15 major surface combatants. It is capable of projecting power within the Indian Ocean basin and occasionally operates in the South China Sea, the Mediterranean Sea and the Arabian Gulf. Fleet introduction of the Brahmos cruise missile and the possible lease of nuclear submarines from Russia will add significantly to the Indian Navy's flexibility and striking power.
Although small, the Indian Coast Guard has been expanding rapidly in recent years. Indian Navy officers typically fill top Coast Guard positions to ensure coordination between the two services. India's Coast Guard is responsible for control of India's huge exclusive economic zone.

         Indian Air Force is becoming a 21st century force through modernization, new tactics and the acquisition of modern aircraft, such as the SU-30MKI, a new advanced jet trainer (BAE Hawk) and the indigenously produced advanced light helicopter (Dhruv). In June 2007, the Indian Government announced intentions to release a request for proposals for 126 multi-role combat aircraft for the Indian Air Force.
