DMC Guardsmen can be easily recognized by their distinctive, black uniforms consisting of: pair of tactical boots, cargo pants, long-sleeved shirt, pair of tactical gloves and face-covering balaclava as well as tactical armored vest and helmet.
Guards patrol the area around the DMC Gate, attacking any monsters and gangers they encounter. Unlike the real denizens of the Michigan wildlands, guards are only outside of the city walls for eight-hour shifts, returning back to the base once their work-day is over. Because of that, guards do not gather any loot, nor do they look for it, concentrating on the patrol duty instead. However if attacked, guards may loot the player.
Initially, the guards are neutral towards the player's character and, unless otherwise provoked, will usually leave him alone. If engaged in friendly manner, they are even willing to answer a quick question or two, but tend to react poorly, and with little patience, to people asking inappropriate ones.
Warning: If threatened or attacked, guards will permanently flag the player's character as hostile.
DMC Guards tend to engage into combat with any gang members, both Bad Muthas and Blue Frogs, on sight. They tend to tolerate the looters more, only engaging them occasionally, usually forcing them to run away.
The guards are extremely dangerous opponents, mostly due to their second-to-none equipment. They are all skilled in ranged combat, armed with combat shotguns and .45 calibre pistols, and wearing heavy tactical vests and helmets.
One way to defeat one of them is to lure a single guardsman into someplace remote, preferably where combat starts at short range (like ruins or forest), get close using cover and engage in hand-to-hand combat. You can even kill them in one hit with a broad spear, melee, strong and unstoppable.
The most efficient way to defeat a DMC Guard is to get Night Vision, either head-worn, or via Augmentation. Then, it's simply a matter of waiting until Nighttime, then sneaking up to the guard and beating him to death. Using this method, it's very easy to farm enough money to buy anything your heart desires. Doing the Saginaw questline and getting NVGs from it,. then hunting guards, will allow you to farm enough money for augmentation, especially when mixed with killing Liza and selling all the YpcV to the Hatter for $4000. Then, it's simply a matter of killing a few guards to get to $6100, then permanently being able to hunt guards for cash.
DMC Guards have the unique ability to call in the support of a Drone if attacked. Those Drones are heavily armored and armed with the extremely deadly Gauss guns. They stay on the battlefield only for short periods of time but are capable of causing extensive amounts of damage. Characters not prepared for a very hard battle should avoid such situations at all cost. Only attempt to take on a Guard with a drone if you are geared with the most advanced equipment available, and even then, remember that retreating is always an option.
