The AN/GSG-10 Tactical Fire Direction System (TACFIRE) was used by the American Army for computerized artillery fire-control. The system used radio and wire communications between observation elements such as forward observers, electronic surveillance devices such as the FireFinder anti-artillery radar, and command and control elements to coordinate and manage artillery assets.

The system was unfortunately too rigid to properly address the fluidity of the modern battlefield, and was often replaced by simple voice commands. The system was finally disbanded in 1993, and replaced by the Initial Fire Support Automated System (IFSAS), which was in turn replaced by the Advanced Field Artillery Tactical Data System (AFATDS). Neither has properly addressed the reality that the target of a fire mission may change position rapidly in the course of battle (see fog of war.)
