The Indian subcontinent is home to two of the largest armies on Earth. Not only are the armies of India and Pakistan both larger in personnel than the U.S. Army, but they have stood at alert facing one another since the dissolution of the British Indian Army in 1947. The two armies have clashed four times in the past seventy years, and may yet do so again in the future.
The Indian army is the primary land force of the Indian armed forces. The army numbers 1.2 million active duty personnel and 990,000 reservists, for a total force strength of 2.1 million. The army’s primary tasks are guarding the borders with Pakistan and China and domestic security—particularly in Kashmir and the Northeast. The army is also a frequent contributor to United Nations peacekeeping missions abroad.
The army is structured into fourteen army corps, which are further made up of forty infantry, armored, mountain and RAPID (mechanized infantry) divisions. There is approximately one separate artillery brigade per corps, five separate armored brigades, seven infantry brigades and five brigade-sized air defense formations.
Infantry and mountain divisions are mostly assigned to the mountainous North and Northeast regions, where manpower intensive counterinsurgency and mountain warfare forces are important, while infantry, RAPID, and armored formations sit on the border opposite Pakistan.
