SAM site (Renegade)

The Sam Site is an Ground-to-Air defense building that is extremely effective versus air units. Taking them out (usually a secondary objective in many missions) allows for air support and reinforcements. There may be several of them to destroy though. They have extremely light armor and are very small, making them easy to destroy with just a chain gun. Although, quite commonly there is a contingency of guards ranging from soldiers to Black Hand to Stealth Tanks (in single player only).
