The Army and Air Force of the United States have been trained for close air support.
U.S. Marines trained for close air support in February with Navy SEALs and Army Green Berets. Immediate air support refers to attacks by fixed- or rotary-wing aircraft on enemy objectives near friendly troops. Joint tactical air controllers are essential for guiding bombs to targets, frequently determining the difference between a successful hit and an accidental friendly fire. Before a close air support operation may be authorized, the U.S. military must complete a stringent checklist known as the “9 lines.” There is no room for error when providing close air support to friendly troops.
The training focused on the capacity of the unified force to integrate and develop CAS techniques. These lines provide the target’s elevation, description, and coordinates, as well as the location and egress of friendly forces. The JTAC is not infallible; deadly errors have occurred in the past, yet, it is essential to close air support missions.
