In Pakistan, the Pakistan military is responsible for external defense but also has a domestic security role; its chief external focus is India; the military is the lead security agency in many areas of the former Federally Administered Tribal Areas (FATA) and has for decades conducted operations against various internal militant groups; it is also one of the longest serving and largest contributors to UN peacekeeping missions; China is its closest security partner

the military operates largely independently and without effective civilian oversight; it has ruled the country for more than 30 years since independence in 1947 and continues to play a significant role in Pakistan's political arena; it also has a large stake in the country’s economic sector and is involved in a diverse array of commercial activities, including banking, construction of public projects, employment services, energy and power generation, fertilizer, food, housing, real estate, and security services

Pakistan has fought four wars and several skirmishes with India; three of the wars have been over the disputed region of Jammu and Kashmir, the status of which has been unsettled since the UK's 1947 withdrawal and the partition and independence of India and Pakistan; a fragile cease-fire was reached in 2003, revised in 2018, and reaffirmed in 2021, although the militarized Line of Control which serves as the border remains contested, and India has accused Pakistan of backing armed separatists and terrorist organizations in the territory New Delhi controls; in the Spring of 2025, Indian held Pakistan responsible for a terrorist attack in India-controlled Kashmir and retaliated, sparking a brief cross-border conflict involving aircraft, artillery, drone, and missile strikes

the Kashmir dispute also includes the Siachen Glacier, located in the Karakoram Mountain Range, which was seized by India in 1984 with Pakistan attempting to retake the area several times between 1985 and 1995; despite the 2003 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 (2025)
