After the Indo-Pakistani War of 1947, recommendations for establishing an elite commando division within the army were accepted. Commissioned in 1956 with help from US Army Special Forces, the Pakistan Army's Special Services Group (SSG) is an elite special operations division; its training and nature of operations are roughly equivalent to British Special Air Service (SAS) and US Army Special Forces and Delta Force. Tentative estimates of the division's size are put at four battalions but the actual strength is kept highly classified.
