Full Spectrum Warrior (2004)

A very clear two-team lesson: Alpha keeps an enemy pinned while Bravo moves between cover, then their roles can swap. The manual distinguishes ordinary fire, engagement and full suppression; full suppression spends ammunition quickly and exposes the firing team to threats outside its chosen sector. Wounded soldiers need evacuation, and excessive casualties fail the mission rather than becoming an acceptable campaign cost. Its fictional Zekistan setting reflects its era. This is an older PC release, so allow for compatibility troubleshooting before choosing it as your easiest starting point.
