Mars City Security

Mars Security, also shortened Mars-Sec, is an unit of low-ranking marines only featured in Doom 3. The Mars Security unit was created by the UAC to guard all areas of Mars City. Normally, the Mars-Sec makes daily patrols in the base. However, many of the Mars-Sec members became insane for some reason. For example, a Mars-Sec put money into a coffe machine and it didn't give him the coffe he paid. Then, he lost his self-control and shot himself with a Plasma gun. He shot himself so much plasma that it would have been enough to power up an entire building. Many of the Mars-Secs doubted if much firepower is required to have the base save. In the events of Doom 3, during the invasion, almost all of the Mars-Sec units turned into Z-secs, their Zombie counterparts, although a few survived the initial shockwave and fought the creatures of hell. In the expansion - Ressurection of Evil - a similar shockwave existed, although with no survivors.

Known members
Some of these Doom 3 characters were known to be Mars-Secs before the invasion begun. This are:


 * Grant Baston
 * T.Brooks

Equipment
Usually a Mars-Sec wears a Helmet with a type of visor and others have like a breather helmet for the surface areas. The Mars-Secs usually wear light weaponry: The Pistol, the Shotgun and most commonly the Machine Gun. If one wants to count Commandoes to the Z-Sec family too, the are also armed with a dangerous Chain Gun or a tentacle. Z-Secs are the player's main enemy until midgame, where they get replaced by harder foes.
