They belong to another branch of the military-the United States Air Force (USAF)-but the Cav patch they wear on their left shoulder makes them unmistakable members of the FIRST TEAM.

With forward air control (FAC) parties supporting each of the division's brigades, the Air Force pilots' primary missions are to provide visual reconnaissance, control and mark Air Force air strikes and adjust artillery.
Location 2 of the Air Force's 5th Weather Squadron provides 1st Cav ground

twice-daily basis. Drawing on field reports from their own teams as well as Path
Finders at forward areas. The observers play a key role in allowing commanders
to consider potential weather threats before completing tactical plans.
