This includes the devices and means used for the recognition and identification of friendly forces. The most common types of visual signals are hand-and-arm, flag, pyrotechnic, and ground-to-air signals. However, Soldiers are not limited to the types of signals discussed and may use what is available. Chemical light sticks, flashlights, and other items can be used provided their use is standardized within a unit and understood by Soldiers and units working in the area.
