In India, the Indian military performs a variety of missions; it is primarily focused on China and Pakistan and territorial defense, while secondary missions include regional power projection, UN peacekeeping deployments, humanitarian operations, and support to internal security forces; it has fought in several significant conflicts and counterinsurgency operations since 1947 and regularly conducts large-scale exercises; the military may act internally under the Armed Forces (Special Powers) Act (AFSPA) of 1958, an act of the Indian Parliament that granted special powers to put down separatist movements in "disturbed areas"; the AFSPA of 1958 and a virtually identical law, the Armed Forces (Jammu & Kashmir) Special Powers Act of 1990, have been in force since 1958 in parts of northeast India, and since 1990 in Jammu & Kashmir

the Army is organized into 14 operational corps; the basic field formations under the corps are approximately 40 armored, artillery, infantry, mechanized, or mountain infantry divisions; there are also a number of independent airborne, armored, and artillery brigades, as well as special operations forces; in 2023, the Army announced that it was reorganizing its operational corps and divisions into division-sized “integrated battle groups,” which the Army assessed would be more agile and flexible

the Navy is a blue water force that operates in seas stretching from the western Mediterranean to the Strait of Malacca and the western Pacific; it routinely conducts months-long deployments, exercises with other navies, and conducts a variety of missions such as counter-piracy, humanitarian, and naval diplomacy; its principal ships include two aircraft carriers, more than 50 destroyers, frigates, corvettes, and large patrol vessels, and nearly 20 submarines, including two with ballistic missile capabilities; the Navy also has several combat aircraft and anti-submarine warfare helicopter squadrons, as well as a marine amphibious brigade and a marine commando force

the Air Force is one of the World’s largest with more than 600 British-, French-, Russian/Soviet-, and domestically produced combat aircraft, plus nearly 500 combat helicopters; the tri-service Strategic Forces Command manages all of India’s strategic missile forces 

the short 1962 Sino-India War left in place one of the World’s longest disputed international borders, resulting in occasional standoffs between Indian and Chinese security forces, including lethal clashes in 1975 and 2020; meanwhile, India and Pakistan have fought several conflicts since 1947, including the Indo-Pakistan War of 1965 and the Indo-Pakistan and Bangladesh War of Independence of 1971, as well clashes over the disputed region of Kashmir (the First Kashmir War of 1947 and the 1999 Kargil Conflict); a fragile cease-fire in Kashmir was reached in 2003, revised in 2018, and reaffirmed in 2021, although the Line of Control remains contested, and India has accused Pakistan of backing armed separatists and terrorist organizations in Jammu and Kashmir where Indian forces have conducted counterinsurgency operations since the 1980s; in addition, India and Pakistan have battled over the Siachen Glacier of Kashmir, which was seized by India in 1984 with Pakistan attempting to retake the area at least three times between 1985 and 1995; despite a cease-fire, both sides continue to maintain a permanent military presence there with outposts at altitudes above 20,000 feet (over 6,000 meters) where most casualties are due to extreme weather and the hazards of operating in the high mountain terrain of the world’s highest conflict, including avalanches, exposure, and altitude sickness (2023)
