Base Facilities/SAM Site
The SAM site is an unmanned, expendable installation that can be placed anywhere in the world to automatically engage detected UFOs with surface-to-air missiles. It is cheap to build and highly useful, but its camouflage is not very effective. Alien craft may detect the missile launches and attempt to destroy the site once they find it. The SAM site is sturdy but will succumb to repeated bombing. Missile reloads are delivered free to our sites by UN forces.
