The quadrupedal GS-54 Guard is among the most well-known SecurityMech designs, named alongside the likes of the Copper, Pacifier and Inquisitor.[1] It is not spelled out if the Guard is built to BattleMech specifications or as an IndustrialMech, although context and it being listed among "commercial-grade" SecurityMechs suggests the latter. Exact stats for the Guard have not been published so far.

The Guard should not be confused with the (apocryphal) Guardian which is also a machine gun-toting 15-ton SecurityMech (albeit one expressly built as a BattleMech).


The Guard is chiefly used on heavily populated worlds in the Capellan Confederation.[1] In 3028 the design was also found among the Draconis Combine's Civilian Guidance Corps PoliceMech forces on An Ting,[3] suggesting the Confederation had exported the design to the Combine at least.

Described as an "awkward quadruped monstrosity of questionable Capellan workmanship"[3] but also as "fairly nimble"[4] and "surprisingly swift on its four legs",[5] a Guard was shown to be capable of preventing a Griffin from closing with it in the confines of a city using lateral movement.[5]

Weapons and Equipment[edit]

The Guard is armed with twin machine guns.[1] No other weaponry is mentioned, though it is overall described as "weakly armed and armored".[3]

An ambiguous scene[6] features a pilot ejecting from a SecurityMech that may or may not have been a Guard from the context; this is noteworthy insofar as ejection seats are automatically included on BattleMechs but are an extra piece of equipment on IndustrialMechs.
