Command & Conquer: Red Alert 2 Tips

Bye, Bye Terror Drome
If an enemy Terror Drome enters any of your vehicles, place it in the Repair Depot and the effect of the Terror Drome will disapear and the unit that was effected will not be destroyed. (A waste of funds but is very helpful to the unit.)

A Repair IFV (IFV combined with an Engineer) can also remove Terror Drones.
