The Communication Handbook
Communicators are experts in radio telephony, communicating vital transmissions across the battlefield in quick succession can often save lives, and lead to a successful mission.
The JTAC or Forward Air Controller ("FAC") is a player who is tasked with coordinating air elements in the support of ground forces and frequently is assigned to the company headquarters element. The FAC is expected to be knowledgeable in the employment of any CAS elements, be they fixed-wing (jets) or rotary-wing (helicopters). The more familiar the FAC is with the aircraft, the better they will be able to direct its employment. The best FACs have extensive experience as a CAS aircraft pilot.
The Forward Observer or "FO" is a player who is tasked with coordinating artillery support for the platoon. They are expected to be knowledgeable in all things artillery, from the types of rounds to use, how to call for fire, how to adjust fire, and everything in between.
Joint Fires Observers or JFOs are able to request, control, and adjust joint mortar, Field Artillery (FA), and Naval Surface Fire Support (NSFS) systems; provide targeting information for A-10, AC-130, and other Close Air Support (CAS) aircraft and joint fire support planning at the company level. Additionally a JFO is trained in controlling multiple ground and air based fire support assets at the same time, ensuring the different assets are deconflicted by time, lateral or vertical space, or a combination of the two tactics.
