In August 1990, 2nd LAAM Battalion flew in four firing units in two missile batteries to cover the large Marine Corps Area of Operations during Operation Desert Shield. Initially Battery A/2, was established in firing positions north of Shaikh Isa Air Base in Bahrain while Battery B/2 established a firing unit north of King Abdul Aziz Naval Base near Jubail, Saudi Arabia. The command and control of these HAWK batteries ran through the Tactical Air Operations Center run by Marine Air Control Squadron 1 (MACS-1) which was integrated into the Saudi Arabian Royal Air Force Easter Sector Command Center in Dhahran. In early September 1990, these Marine Corps HAWK units were the only Medium Altitude Air Defense in Saudi Arabia. As the buildup continued, 2nd LAAM took part in force on force engagements against friendly aircraft in Saudi Arabia.
