Battlemech - Bushwacker
The Bushwacker was originally a failed BattleMech 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.

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.
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.
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.
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
In MW:PR 3051 the Bushwacker is suited best for long/medium range support tasks. The Bushwacker's narrow porfile makes it a hard to hit target, and while not strongest medium, the Bushwacker is a scary adversary. Keep the Bushwacker operating behind your assault mechs for maximum effectiveness.
