 Although F-16As of the Pakistan Air Force (PAF) did not see combat in the 1999 Kargil War, they were initially employed in patrolling the border to ensure Indian Air Force (IAF) fighters did not cross the line of control.Later in the war, lack of spare parts due to sanctions imposed on Pakistan forced the PAF to withdraw its F-16 fleet from regular patrol duties.The PAF's main opposition was the MiG-29, used by the IAF to provide fighter escort for Mirage 2000s which were attacking enemy targets with precision guided munitions.
