TACFIRE

From Wikipedia, the free encyclopedia

The AN/GSG-10 TACFIRE system automated Field Artillery command and control functions. It was composed of computers and remote devices such as the Variable Format Message Entry Device (VFMED) and the Digital Message Device (DMD) linked by digital communications using existing radio and wire communications equipment.

The last TACFIRE fielding was completed in 1987. Replacement of TACFIRE equipment began in 1994. TACFIRE was a second generation mainframe computer developed primarily by Litton Industries for Army Division Field Artillery. It had two configurations, Division and Battalion level, housed in mobile command shelters. Components of the system were identified using acronyms.
