Ghost squads take orders in Tom Clancy's Ghost Recon, Red Storm's 2001 shooter about commanding specialists in a near-future war. The GameCube version is a console port of that tactical game, with fireteams still the unit you actually play.
A planned route through a treeline matters more than a sprint, and losing a named Ghost hurts the next mission. The war is a near-future clash, not a historical beach, and the cube port keeps the squad view rather than turning it into a lone-hero campaign.
Red Storm's first Ghost game is this command puzzle. Later Ghost sequels added fancier kits; the cube port is the early doctrine.
