Well, then, in that case....
Warrior S-9 VTOL - with stealth armor & a +5 movement modifier, no one is going to ever successfully return fire on it while it lays down that ELRM barrage.
DOL-1A2 Dola - It's a Spider with TAG and a vibroblade. Who hasn't wanted that?
TSG-9DDC Ti Ts'ang - Yes, it's completely useless without an elite pilot, but with one, the TC/X-Pulse lasers and Lance can tear up just about any opponent.
THR-C4 Thunder - Pulls down a +3 jumping mod and can indirect fire a 20 point face-crusher out to 18 hexes? Move over, Archer! That's my kind of fire support!
TR-13G Transit - The Long Tom Cannon under the Aerospace rules makes the Improved Heavy Gauss Rifle look like a silly waste of resources.
Vengeance-DC class Pocket Warship - Swarms of fighters and swarms of missiles! Few Pocket Warships will be able to touch the firepower of a solid Vengeance-DC group!
