Behemoth (Stone Rhino) 4, 5 and 6

[Deadborder]

I'm curious as to the origin of these three variants; they're in RS 3055U and they're on the Master Unit List, but I don't think I've ever seen any fluff text of the like on them. MUL also gives their intro dates as the early 29th century, thus predating the reseen Behemoth (Stone Rhino) 2 and 3.

Is there any background to these designs that I've missed or is it something not yet covered?

No background to these designs has been published. Their origin is Mechwarrior 2: Ghost Bear's Legacy.

Obviously, one of the MW2 GBL designers in turn paid hommage to the BD Behemoth.
