As work progressed on "Full Spectrum Warrior", ICT developed another real-time tactical decision-making game with Quicksilver Software entitled "Full Spectrum Command" for the US Army's Infantry Captains Career Course, with the first-person perspective of a Company Commander. As the application was designed to play on a desktop PC (unlike the Xbox), no commercial release was necessary. "Full Spectrum Command" gave rise to a sequel developed for the US Army and Singapore Armed Forces (version 1.5). A related ICT/Quicksilver title, "Full Spectrum Leader", simulates the first person perspective of a Platoon Leader.
