I'm pretty sure the setup for the mech is homing missiles, iron claw, 2-walker. That translates to the Byakko model, apparently. (I'm not sure if we'll ever have cause to include flags for all 64 models, though...) The Ragnarok mech, meanwhile, is of the Berserker model. The other two models in the game are Brownies (popcorn enemies) and Gargoyles (the ones with bombs, rifles, and beam sabers).
