The UrbanMech was designed for just what its name suggests, urban combat and defense. This was achieved by starting with a cheap, easily-produced chassis, giving it six tons Durallex armor to rival the protection found on many medium-weight BattleMechs, and mounting a pair of Pitban 6000 jump jets for a jumping distance of 60 meters. The trade-off was that it could only mount the miserly Leenix 60 engine, making the UrbanMech the slowest light 'Mech in existence with a cruising speed of 21 km/h and top speed of only 32.4 km/h. This was a severe disadvantage if the 'Mech attempted to fight in open country - something for only the foolish or desperate - but off-set by the fact that fighting in the close confines of a Star League city left little room to maneuver anyways and the UrbanMech's low profile made it difficult to target. Thus the 'Mech was primarily used for fighting guerrillas and other light 'Mechs in an urban environment, an arena where it also achieved some success fighting medium and even heavy-weight 'Mechs. Standard tactics for an UrbanMech lance was to split up into its constituent parts and occupy various buildings in order to snipe the enemy before falling back to the next defensive line.
Large numbers of UrbanMechs were produced by Orguss Industries from 2675 until the destruction of their assembly lines and could be found in all of the armies of the Successor States. However most military leaders saw the slow little 'Mech as a liability, confining their stockpiles to garrison duty or stripping them of parts. This dismissive attitude towards the UrbanMech saved it from the ravages of the Succession Wars and ensured its continued use into the 31st Century. The Capellan Confederation remained the largest and only user of UrbanMechs to actually deploy them for front-line duty, a result of the devastation of the Fourth Succession War and their desperation for any 'Mech to replenish their losses. The Confederation Reserve Cavalry and Capellan Defense Force had the lion's share of UrbanMechs, followed by the Tikonov Republican Guard and St. Ives Armored Cavalry; outside the Confederation the Federated Suns' Capellan March Militia fielded the largest number of UrbanMechs thanks to the fact it was mostly composed of captured Capellan equipment. It's prominence within the Confederation meant the UrbanMech was among those 'Mechs within the CCAF to receive upgrades following the recovery of lostech; the other States followed suit with much less priority over improving other 'Mechs. Despite this the sheer costs necessary to replace the UrbanMech's engine and increase it's top speed meant even the Confederation limited their refit packages to improving the weapons and armor only.
 Weapons and Equipment
The UrbanMech packs a powerful punch for its size. The standard version carries an Imperator-B Autocannon/10 in its right arm and as a back up weapon it carries a Harmon Light Small Laser in the left arm for suppressing infantry. With these two weapons the UrbanMech can constantly harass, or if piloted by an experienced enough MechWarrior, down 'Mechs up to twice its own size. A single ton of ammo for the autocannon, located in the right torso, leaves little endurance for a prolonged fight, though it fits in perfectly with the hit-and-run nature of the 'Mech; one way or another most observers agree the UrbanMech is good for about two minutes of combat.
- UM-R50 (exact designation apocryphal)
- This was an early variant without arms. The idea was to give the 'Mech a smaller silhouette in combat. However, the drawbacks of having no arms turned out to be greater than benefits and this particular variant is generally regarded as a failure. Only very few units of this subvariant survived into 3025.
- Generally associated with the Capellan Confederation, who have modified a few of their UrbanMechs in this fashion, the -R60L is an upgrade to make the UrbanMech twice as deadly as the -R60 version. The -R60L sacrifices two tons of armor, allowing it to replace the Imperator-B Autocannon/10 with an Imperator-Zeta Autocannon/20 that is capable of downing most light 'Mechs and severely damaging most medium 'Mechs in a single salvo. Besides the thinner armor this modification comes with a very limited ammunition supply, which made it unpopular. BV (1.0) = 443, BV (2.0) = 470
- This is the official upgrade kit for the Capellan Confederation's UrbanMechs, distributed for field modification since before 3050. It replaces the Autocannon/10 with an LB-X Autocannon/10 version and retains the small laser; it also substitutes a Small Pulse Laser for the machine gun in the left torso. Given that neither the regular -R60 nor the -R50 or -R60L variants mount a machine gun, this indicates that the previous standard Capellan model was not one of those, but a different subtype with a machine gun (see below). BV (1.0) = 494, BV (2.0) = 540
- This Free Worlds League variant upgrades the autocannon to an Ultra Autocannon/10 and the laser to an ER Small Laser. This is all made possible by the upgrade to five tons of Ferro-Fibrous armor and the removal of the eleventh heat sink. While the ultra-class autocannon provides superior firepower, it can also eat through the single ton of ammunition at an alarming rate. BV (2.0) = 589
- The Federated Suns -70 model is an upgrade that has greater potential than the -R63. The -70 uses Ferro-Fibrous armor and mounts a Rotary Autocannon/5, which can fire up to six times the normal rate of fire, and carries two tons of ammunition. For backup weapons, it carries an Extended Range Medium Laser and Extended Range Small Laser. BV (1.0) = 604, BV (2.0) = 724
- This variant of the UrbanMech replaces the standard weaponry with an Arrow IV missile launcher and ER Medium Laser. It requires an Endo Steel chassis and Small Cockpit to provide room, and the UrbanMech can only carry ten rounds for the Arrow system. Despite these limitations, it is still a decent fire support unit. BV (2.0) = 603
- Machine Gun version
- There is evidence in the Technical Readout: 3050 Revised (in the entry for the UM-R63 UrbanMech) that there is a contemporary variant of the classic UM-R60 that mounts a Machine Gun in the left torso. Although no subtype designation is known, the Capellan Confederation apparently used primarily this subtype: Their later UM-R63 upgrade was in fact based on this subvariant instead of the standard -R60, as the -R63's Small Pulse Laser is installed in the place of the Machine Gun. It can be speculated that this variant's Machine Gun and half a ton of ammo take the place of the curious and largely useless eleventh heat sink found on the standard -R60 and most other models including even the -R63. BV (1.0) = 448, BV (2.0) = 492
