The 6th Lancers is an armoured regiment of the Pakistan Army. Previously, it was known as the 6th Duke of Connaught's Own Lancers (Watson's Horse), and was a regular cavalry regiment in the British Indian Army. It was formed in 1921 by amalgamation of the 13th Duke of Connaught's Lancers (Watson's Horse) and the 16th Cavalry. The regiment and its predecessors have seen active service on the North West Frontier, in Egypt during 1882, in China during the Boxer Rebellion, the two World Wars and the Indo-Pakistani War of 1965. On the Partition of India in 1947, the regiment was allotted to the Pakistan Army, where it remains in service today.

The Indo-Pakistani war of 1965, also known as the second India–Pakistan war, was an armed conflict between Pakistan and India that took place from August 1965 to September 1965. The conflict began following Pakistan's Operation Gibraltar, which was designed to infiltrate forces into Jammu and Kashmir to precipitate an insurgency against Indian rule. The seventeen-week war caused thousands of casualties on both sides and witnessed the largest engagement of armored vehicles and the largest tank battle since World War II. Hostilities between the two countries ended after a ceasefire was declared through UNSC Resolution 211 following a diplomatic intervention by the Soviet Union and the United States, and the subsequent issuance of the Tashkent Declaration. Much of the war was fought by the countries' land forces in Kashmir and along the border between India and Pakistan. This war saw the largest amassing of troops in Kashmir since the Partition of India in 1947, a number that was overshadowed only during the 2001–2002 military standoff between India and Pakistan. Most of the battles were fought by opposing infantry and armored units, with substantial backing from air forces, and naval operations.
