These large robotic YTX machines have been known to seek and destroy pretty much everything. Sometimes however, they have been known to have been destroyed, even though they are at least 100 times larger than an average tank. A good tactic for destroying them would be to use an APG-7 with quite a lot of missiles. Or, just reach underneath it, remove the turret's Scrots and get inside the machine, there you can sometimes find a control center, this only happens once in a hundred INFINITIES though. Which is a shame as they can be extremely powerful.
A few have been known however to be hijacked by Fakegees who were fighting back against the YTX Ballistic Creation Chamber, this was quite hard to do though as the machine has many un-needed wires to confuse the hijackers.
