TACFIRE

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), the Digital Message Device (DMD) and the Firefinder Field Artillery target acquisition radar system linked by digital communications using existing radio and wire communications equipment. Later in its service life, it also linked with the Battery Computer System (BCS) which had more advanced targeting algorithms.

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 Divisional Field Artillery (DIVARTY) units. It had two configurations, Division and Battalion level, housed in mobile command shelters. Field Artillery Brigades also use the Division configuration.

Components of the system were identified using acronyms:

- CPU (central processing unit)

- IOU (input/output unit)

- MCMU (mass core memory unit)

- DDT (digital data terminal)

- MTU (magnetic tape unit)

- PCG (power converter group)

- ELP (electronic line printer)

- DPM( digital plotter map)

- ACC (artillery control console)

- RCMU (remote control monitoring unit)

The successor to the TACFIRE system is the Advanced Field Artillery Tactical Data System (AFATDS).
