GDI Tank Trap

The GDI Anti-Tank Barrier (Tank Trap)

This is probably the most underrated unit in the game.  I've only started using it a few month ago after seeing how much damage they could do to even quite strong tanks. When you get attacked with those things and the attacker is a few levels below it and don't deal with them early on, they won't stand much of a chance once they get to the real firepower.  They will cause decent damage at any level, it's only goal is to hit tanks and does a damn good job at it.

It's ideal for initial and early damage.  If you use lots of them, make sure to add in a sniper or two to avoid any Commando problems.  It has a similar effect as what you'd expect from a mine.

Definitely one of my favorite defense unit.  If an opponent is un-prepared (You'd be shocked) then it could mean the difference between taking serious damage or destroy every vehicle that comes in without even trying.  I've had a level ~25 attack, he stopped trying...
