Mars City Security

Mars City Security, also shortened to Mars-Sec, is, as the name suggests, the regular security guard unit of Mars City and the adjoining UAC facilities. Mars Security are the UAC personal security contractors (therefore they are under the UAC payroll). They have different body armor, rank structure and uniforms than the Marines. In any case, the Mars-Sec, like the Marines, fall under the authority of Master Sergeant Thomas Kelly. While the Mars-Sec seem to share many duties with the Marines, it appears that the Mars-Sec serve as the day-to-day regular UAC Security Guard force. Marines, on the other hand, tend to have more specialized jobs, such as being tasked with guarding special areas around the base (Marine Command for instance), as well as accompanying science teams being sent through the Portal. The security team for the Delta Labs (Marines and Mars-Sec alike) are specially selected, due to the unique nature of research conducted inside Delta labs. Because UAC provides major funds and weapon research for the military, the government established an active duty Marine base on Mars to assist the UAC with extra security while the UAC continues to conduct research for new military weapons (Marine guards are under the military payroll).

Some of the Mars-Secs and marines wondered why the Mars facility needed the defensive and security equipment it had. During the demonic invasion, almost all of Mars-Sec was possessed, being turned into Z-Secs (Zombie-Security).

Equipment
A typical Mars-Sec wears a helmet with combat visor, goggles, or use a sealed helmet for outside operations and transit. Unlike the marines who all wear brownish-green armor, the Mars-Sec wear black armor. The Mars-Security unit typically is issued standard weapons like Pistols for their duties. Others may have shotguns. Security guards are also issued PDAs, and use equipment like Sentry Bots, specialized tablet-type PDAs, security keycards, and other gear. They also work with and use standard-issue weapons and equipment such as the Enforcer Machine Gun. Some can be equipped with protective Riot Shields.
