The Bushwacker was originally a failed BattleMech concept designed to have a smaller forward profile to make the 'Mech a harder target to hit. The Bushwacker's unique design caused problems with the engine shielding, the side-effects of which manifested themselves as various gremlins in the 'Mech's on board electronics on the prototypes fielded during the Clan Invasion. The 'Mech was redesigned after schematics for an OmniMech known as the Vulture were captured during a raid into Clan territory. Information gleaned from the schematics were used to overcome the aforementioned engine shielding problems. Finding the schematics had given the Bushwacker a second lease on life. Full production of the corrected Bushwacker began just after the Truce of Tukayyid, and the 'Mech has since become a favorite of MechWarriors in the Draconis and Capellan Marches of the Federated Suns.[3][1]

Weapons and Equipment[edit]

The Bushwacker has a top speed of 86.4 km/h and carries nine tons of armor. What the 'Mech lacks in protection it makes up for in range, using its speed to keep enemies at arm's length while using its slew of long range weaponry to slowly wear down enemies.[1]

In an attempt to keep the enemy at as long a range as possible, the Bushwacker carries two Federated 5-Shot LRM-5 launchers. The LRM-5s give it the capability to give some indirect fire support as well as laying down minefields with specialized munitions. These are backed up by a BlazeFire Sweetshot ER Large Laser and an eighty millimeter Mydron Model B Autocannon/10, which give the 'Mech a powerful long range direct-fire punch. A pair of Johnston Minigun Machine Guns are the only short range weapons carried by the 'Mech.[1]


  • BSW-X2 
    Based on the standard Bushwacker, this simple variant removes the ER Large Laser and replaces it with an additional LRM-5 launcher in the torso and a pair of Medium Pulse Lasers. It also drops one heat sink. BV (2.0) = 1,193[5]
  • BSW-L1 
    The L1 variant of the Bushwacker is a configuration that changes the 'Mech to a close combat unit. The only long range weapon on the L1 variant is an ER Large Laser. For close combat, the L1 carries an LB-X Autocannon/20 that can fire either standard or cluster ammunition, adding versatility to the crippling firepower of this extremely deadly close combat weapon. Two and a half tons of additional armor was added to the BSW-L1, giving excellent armor protection. The L1 saw its engine upgraded to a Light Fusion Engine for increased survivability. BV (1.0) = 1,342[6][7] (1,264)[8], BV (2.0) = 1,513[9]
  • BSW-S2 
    The S2 is a variant of the Bushwacker that makes the 'Mech more effective at short to medium ranges. The 'Mech carries an ER Large Laser to allow the 'Mech to engage an enemy at long ranges as it closes. The 'Mech carries an LB-X Autocannon/10, which can fire both standard and cluster ammunition for long to medium range engagement capabilities. For close combat, the 'Mech has two SRM-4 launchers, making it a powerful unit at any range. For added defense, the S2 carries an Anti-Missile System. BV (1.0) = 1,103[6][10], (1,123)[11], BV (2.0) = 1,293[12]
  • BSW-S2r 
    This variant mounts a Plasma Rifle and ammunition in place of one of the SRM launchers and the ER Large Laser of the BSW-2S.[13] BV (2.0) = 1,339[14]

Apocryphal Variants[edit]

Apocryphal Content Starts

The information after this notice comes from apocryphal sources; the canonicity of such information is uncertain.
Please view the reference page for information regarding their canonicity.

These variants presented here were introduced in MechWarrior Online, and thus far have not appeared in any canonical media.

  • BSW-P1 
    A missile boat in the mold of the X2, the P1 moves one of the left-torso LRM-5 launchers to the right torso, retaining the X1's center torso mounted ER Large Laser by replacing the AC/10 with lighter AC/5 and removing the Machine Guns. Removing the CASE, the P1 also exchanges the Ferro-Fibrous armor of the standard Bushwacker for an Endo Steel frame, the extra weight saved allowing it to carry three tons of LRM missiles, two tons of autocannon rounds and mount thirteen double heat sinks.[15]
  • BSW-P2 
    Built for increased field endurance, the P2 moves the X1's ER Large Laser to the right-arm mount that previously held the AC/10 and installs the X2's twin Medium Pulse lasers in the center torso. Retaining the LRM-5s and Machine Guns, any loss in protection by removing the Ferro-Fibrous armor and CASE is mitigated be carrying more standard armor made possible by a swap to an Endo Steel frame. A single ton of missile and machine gun reloads each and sixteen double heat sinks give the P2 good endurance in battle.[15]
  • BSW-HR High Roller 
    While all indications are that Valten Ryder piloted a standard (albeit prototype) BSW-X1 variant, some sources indicate his so-called High Roller was refitted, dropping the left-arm mounted LRM-5 launcher for a brace of three Medium Lasers, exchanging the Ferro-Fibrous armor and CASE for Endo Steel to carry an extra half ton of Machine Guns reloads and an extra double heat sink.[15]

Related 'Mechs[edit]

  • Mad Dog - TharHes's design of the Bushwacker had been complicated by space-constraints within the torso, leading to system glitches. When the Federated Commonwealth encountered the Clans' Mad Dog, the Bushwacker's torso was reorganized based on captured and salvaged samples. The resulting BattleMech was free of glitches, and quickly put into production.[3][1]
  • Barghest - TharHes, at the behest of Archon Katrina Steiner-Davion, constructed a new quad BattleMech based on the Bushwacker. The chassis was modified by moving the legs forward and adding a second pair of legs in the rear, followed by increasing the mass of the chassis by 15 tons.[16]
