Yeah, basically I was asking to form a mechanized unit. Using the more common BA, GDL Standards, IS Standards, Longinus, Periphery Trinity, and Cavalier/Raiden to form the 'infantry' component with tracked IFVs (means some sort of supporting weapon) and heavy tracked armor for some backbone.
Depending on the origin it and time frame some of the suggestions, like the Main Gauche IFV- which I like a lot- might not be available. And while the Plasma Rifle works nicely in the role, I am not sure a MML followed by a LRM rack would not be better choices. As far as the supporting armor options . . . Bulldogs, Pattons, Brutus and Pos. If you really had the cash and past the Jihad Merkava, Moltke, Glory FS and for the really spendy Shark/Fox Morrigu.
