Once purchased from any faction's (except ECA) barracks, basic infantry are trained to capture neutral and enemy buildings (including superweapons).
In order to capture a building, the infantry unit must come very close to building. Capturing a building requires several seconds, during which infantry units capturing building are vulnerable to enemy fire. Base defenses, however cannot be captured.
