[Mobhack]

The "tank transporter" sort of snuck in a few years ago when some third party OOB designers found an exploit that allowed vehicle carry which was really only meant originally to be for LCT etc.

When I found these, I wanted to nuke any such found in the OOBS as being completely outside of the game's scope. But it was eventually decided to leave them in just for those folks who wanted to ignore realism and do "instantaneous tank evacuation", and a unit class was added for them.

Cheers
