The Timber Wolf is a fast heavy OmniMech. A signature design of the Clans' military might, it was arguably the first Clan OmniMech encountered by Inner Sphere forces (as opposed to periphery forces) on The Rock in 3049 by Phelan Kell.
Vaguely resembling a cross-over between the MAD (Marauder) and CAT (Catapult) series, the Timber Wolf was tagged with the Inner Sphere reporting name name Mad Cat on first contact. (The targeting computer on Phelan Kell's Wolfhound' switched between MAD and CAT when trying to identify it; Precentor Martial Anastasius Focht later officially designated it "Mad Cat".)
The Timber Wolf is vastly more powerful than either the Marauder or the Catapult. It uses its speed and firepower to engage an enemy at the range of its choosing. When first encountered by Inner Sphere forces the idea that a heavy 'Mech could move so swiftly while being as heavily armed and armored as the Timber Wolf was inconceivable. With its twelve tons of Ferro-Fibrous armor and arsenal that rivaled that of most assault 'Mechs of the era, it was completely alien to Inner Sphere military planners, commanders, and even the Precentor Martial of ComStar. It technological secrets have since been reverse-engineered by the Inner Spere.
First introduced in 2945, the Timber Wolf was designed by Clan Wolf as a second generation OmniMech along with the Gargoyle and the Naga to replace the aging Woodsman. While the Gargoyle may have been a very capable, fast assault OmniMech, and the Naga may have been an excellent fire-support OmniMech, Clan Wolf (and indeed every other Clan) instantly realized the value of the Timber Wolf; thus, production rights to the Timber Wolf were jealously (and successfully) defended. Only through trade, gifts and battlefield salvage has the Timber Wolf entered the armies of other Clans. Until the invasion of the Inner Sphere, production of the Timber Wolf has been limited to a single facility on Strana Mechty.
