Indo-Pakistani War: The Indian Air Force executes an airdrop of Indian Army units, bypassing Pakistani defences.

The Indo-Pakistani war of 1971, also known as the third Indo-Pakistani war, was a military confrontation between India and Pakistan that occurred during the Bangladesh Liberation War in East Pakistan from 3 December 1971 until the Pakistani capitulation in Dhaka on 16 December 1971. The war began with Pakistan's Operation Chengiz Khan, consisting of preemptive aerial strikes on eight Indian air stations. The strikes led to India declaring war on Pakistan, marking their entry into the war for East Pakistan's independence, on the side of Bengali nationalist forces. India's entry expanded the existing conflict with Indian and Pakistani forces engaging on both the eastern and western fronts.

The Indian Air Force (IAF) is the air arm of the Indian Armed Forces. Its primary mission is to secure Indian airspace and to conduct aerial warfare during armed conflicts. It was officially established on 8 October 1932 as an auxiliary air force of the British India which honoured India's aviation service during World War.

Operation Cactus Lilly, better known as The Meghna Heli Bridge or the Crossing of the Meghna, was an air assault operation conducted between 9 and 12 December 1971 during the Indo-Pakistani War of 1971. It was conducted by the Indian Army and Indian Air Force to cross the Meghna River, bypass a Pakistani stronghold at Ashuganj/Bhairab Bazar and reach Dhaka. The operation is generally regarded as the brainchild of Maj. Gen. Sagat Singh. Without it, Indian forces would not have been able to complete the encirclement of Dhaka and it would likely have led to a lengthening of the war.

The Indian Army (IA) is the land-based branch and largest component of the Indian Armed Forces, making it the world's second-largest army and the fourth most powerful military globally. The President of India is the Supreme Commander of the Indian Army, and its professional head is the Chief of the Army Staff (COAS). The Indian Army was established on 1 April 1895 alongside the long established presidency armies of the East India Company, which too were absorbed into it in 1903. Some princely states maintained their own armies which formed the Imperial Service Troops which, along with the Indian Army formed the land component of the Armed Forces of the Crown of India, responsible for the defence of the Indian Empire. The Imperial Service Troops were merged into the Indian Army after independence. The units and regiments of the Indian Army have diverse histories and have participated in several battles and campaigns around the world, earning many battle and theatre honours before and after Independence.
