In military tactics, close air support (CAS) is defined as air action by fixed or rotary-winged aircraft against hostile targets, that are in close proximity to friendly forces, and which requires detailed integration of each air mission with fire and movement of these forces. On the other hand, Aviation Ordnanceman are aircraft armament (weapons) specialists in charge of storing, servicing, inspecting and handling of all types of weapons and ammunition carried on military aircraft. Military planes carry guns, bombs, torpedoes, rockets, and missiles to attack the enemy on the sea, under the sea, in the air, and on land.
