*eyes squint* I make of it you don't know the real name of the battlemech! Its a timberwolf! ;)
Actually it's two words,
Timber Wolf - Pedantic mode
The truth is that I habitually use the Inner Sphere codenames for Clan 'Mechs (with one or two exceptions) in discussion or the like. There's a number of reasons for this, not the least of which is that the writers follow the same pattern and use the Inner Sphere codenames as a primary designation. Plus if you look from an in-world perspective, the teeming untold billions of the Inner Sphere will call it a
Mad Cat; it's only a teeeny tiny infentessimal minority who call it a
Timber Wolf. Hell, the Sharks named the Mk II and III
Mad Cat as the name had a higher degree of recongition.
Now if I was writing In Character as a Clan character, then I'd call a 'Mech by its Clan name. Hell, there's even a moment in a stillborn BC story concept where this is an issue.
