Now on to the story(for those who don't know why the Marauder was removed from Battletech):
Like around the Mid 1990's, my favorite 'mech, the Marauder, suddenly disappear. When I first played Mechwarrior 2: Mercenaries and got the revised edition of the 3050 Technical Readout and I see no Marauders! Where did it go? I was in a loss.
Battletech was inspired by Japanese anime and manga of giant robots beating the crap out of eachother. When the game was first published under the name of \"Battledroids\", the fledging FASA corporation was nearly sued by Lucasfilm, Ltd. for their usage of the word 'Droid'. FASA's meager legal division was swamped by the regiments at Lucas's fingertips. After a quick re-write, Battletech was born, with a Warhammer, guns blazing, striding across the box front in 1985. To jump-start its game, as well as keep the anime feel, FASA used the robot designs from three anime programs: Macross, Crusher Joe, and Dougram.
Meanwhile in the mid-1990's, FASA argues that they had permission from various Japanese production companies to use their designs. Harmony Gold, the producers of Robotech(the Americanized version of Macross), argued otherwise. As the legal forces of both relatively new and relatively strong companies poised for battle, FASA again pulled the better part of valor and settled out of court, removing the Macross-based designs from future publications but keeping the designs in the history of the Battletech universe.
So disappeared the Wasp, Stinger, Valkyrie, Ostscout, Phoenix Hawk, Rifleman, Ostroc, Ostsol, Crusader, Archer, Warhammer, and Marauder.
The Marauder 'mech was turned out to be Khyron's Battle Pod in Robotech.
and for a bonus:
Yet the Thunderbolt, Griffin, Shadow Hawk, Wolverine, Locust and the venerable BattleMaster remained>. The WZISS had lost its greatest lead. Extensive research of Robotech and Macross archives revealed nothing that even remotely resembled the lost BattleMaster. The next target of operations was Crusher Joe.
After some searching, the Locust was discovered to be some sort of combat robot in the Crusher Joe anime series. That was it. The lead dried up again. The only hope left was Dougram.
After the Search, they dropped off the Dougram Designs:
BattleTech = Sun's Fang Dougram
----------------------- ------------------
BLR-1G BattleMaster = Soltic HT-128 Bigfoot
GOL-1H Goliath = Abitate F44A CrabGunner
GRF-1N Griffin = Soltic H8-RF Roundfacer
SCP-1N Scorpion = Abitate F35C BlizzardGunner
SHD-2H ShadowHawk = D-7 Dougram (JAKT Type)
TDR-5S Thunderbolt = Hasty F4X Ironfoot
WVR-6R Wolverine = Abitate T-10C Blockhead
My brother told me that the Marauder was removed due to copyright issues.
Meanwhile in 2003 the Marauder was remade into a \"Reseen\" 'mech with an all new appearance.
here's a pic of the \"Reseen\" Marauder:
Not deadly, but in certain CTF maps proved Very annoying. 
But yeah, MW4 was a bit of a flawed game in the end. People tried to improve it with various mods, but they still don't have it perfect.
... really liked it.
