16 February 2016 ATP 3-09.02 6-1 Chapter 6 Survey Computer Systems The forward observer system (FOS) gives FA forward observers the capability to direct and coordinate FA, mortar, close air support, and helicopter munitions onto targets. The FOS gives commanders, fire support officers, fire support teams, and forward observer and survey teams the capability to plan collective actions through maneuver and artillery graphic map displays. It provides storage of survey calculations and control points by FA surveyors. SECTION I – OVERVIEW 6-1. The handheld terminal unit (HTU) is part of the common hardware program, and therefore, software for other military systems can be loaded on the HTU. For example, Battery Computer System (BCS) software has been hosted to the HTU. The software loaded on the internal hard drive controls the functions available to an HTU operator. When the FOS software is loaded on the HTU, the operator can function as a forward observer, fire support team (FIST), fire support officer, commander, or a surveyor.
