T-43 Ravager

The T-43 was an extremely powerful tank which was incredibly strong and could wipe out a base in a very short time period, with a 30MM minigun that the driver would've used, AND a very very powerful main coilgun turret, this tank was very difficult to get and was even removed for obvious reasons.

Its overpoweredness ultimately led to its demise, and perhaps the removal of every other vehicle within the legacy vehicles category. It will live on as one of the most powerful things that nobody knows about.

Advantages

 * Extremely powerful
 * Amazingly, relatively inexpensive for its obscene strength
 * Coaxial 30MM minigun means the driver could use it as a distraction for an all-out raid. (But why do that when you could grab a buddy?)

Disadvantages

 * 12000 hit points, which was below average at the time.
 * Inexpensive FOR A TANK OF THAT POWER, if it weren't so good, it would've been a total ripoff
 * Vulnerable to C-4ing

You would've tried to...

 * Avoid XTAMs
 * Keep a gunner with you
 * Used the drivers minigun
