Guard Unit Armory Device Full-Crew Interactive Simulation Trainer (GUARDFIST-II)

Interactive Automated - This mode has a digital interface between the Forward Obserer, Digital Message Device, GUARDFIST II and the Fire Direction Center Battery Computer System. The Forward Observer's requests for fire via the Digital Message Device (Forward Entry Device or FED) are thus sent digitally. The instructor can still override this transmission. The Forward Observer's verbal requests for fire are manually entered by the instructor and this data is digitally transmitted to the Fire Direction Center. Fire Direction Center firing data generated by the Battery Computer System is transmitted to the GUARDFIST II computer via the digital interface.
