Overview:
Called upon to produce an effective light 'Mech for city-fighting, Orguss Industries replied
with the Urban-Mech. Cheap to produce, but potent in its assigned duties, the 'Mech was
manufactured in large numbers, many of which have survived into the present era. Now common
in city garrisons and defense units, the UrbanMech continues as an effective battle weapon.
Capabilities:
At 30 tons, the UrbanMech is only slightly heavier than Wasp and Stinger scout 'Mechs, and
so its slow speed seemed a distinct liability. It was designed for city combat, however, an
environment that severely limits most other 'Mechs. The 'Mech's Durallex Heavy armor
provides considerable protection, and its low, stocky profile makes it a difficult target.
On some models, Orguss Industries followed an unorthodox, armless design. While this
further streamlined the machine's profile, it handicapped the UrbanMech in other ways. The
'Mech was obviously unable to defend itself in hand-to-hand combat, and damage that would
normally have struck the 'Mech's arms was transferred directly to the torso. Thus, armless
UrbanMechs were usually deployed where the likelihood of meeting enemy 'Mechs was small.
The Imperator-B Class 10 autocannon is the UrbanMech's primary weapon. With its low heat
buildup and reliable design, the weapon suited the UrbanMechs hit-and-run fighting style.
The light laser that supports the Imperator is only marginally effective, but is useful in
persuading hostile infantry to keep their heads down.
Variants
As noted above, the major variant of the UrbanMech is the armless version. The
disadvantages of this design proved fatal, and so very few have survived to the present.
House Liao has a few UMs with Imperator-Zeta Class 20 autocannon, but the weapon's heat and
mass have kept the 'Mech from gaining any great popularity.
