RTS Mine Sweeper
The Mine Sweeper is a unit in Army Men: RTS. It can be made via the Barracks. The Hero Hoover is a Mine Sweeper.

Mine Sweepers can deactivate enemy mines, and are the only unit that doesn't have any attacks (if the Radio Operator isn't counted on the grounds that it doesn't directly attack units). The range of their ability seems to be around or slightly above the attack range of units.
