This is probably one of the scariest moments of a supreme commander game as you wonder who's base is going up in flames..
Um my favorite unit of all my RTS games has to be the Nobz from DoW 2, a group of hardy and vicious orks that revel in smashing the enemy into raspberry jam with a small selection of chain-axes or hammers..
I believe he was quoting Starcraft just there...The original post mentions Ghosts, I seem to remember.
Also, I'm unclear on why chainswords and chain-axes have become so popular. A chainsword is quite literally a chainsaw, only wieldable in 1 hand. The chain-axe is even worse: With no blade, the advantage an axe brings (Using momentum to slide the blade through the enemy) is completely lost: A chainsaw cannot utilize that momentum as well as a sharp edge, not by a long shot. I simply don't understand why these would be any more effective weapons than their simple 'sharp edge' equivalents.
To answer the question posed, however, I would have to go with the Emperor Tank, from Generals: Zero Hour. Not only did it have the ability to upgrade a chaingun turret for easy anti-infantry and anti-air, it came equipped with the powerful speaker tower, which allowed for healing to nearby allies, and was even more powerful than it's smaller counterpart, the Overlord. This tank is the tank other tanks wish they could be.
