The Devil's Tongue is a boxy vehicle with two giant horizontal drills located on its front and treads wrapped around the profile of the vehicle. Once it was unleashed on the battlefield, GDI infantry facing it soon learned a whole new meaning of the word "fear".
Tanks containing pressurised napalm are completely enclosed within the vehicle, as are the powerful engines required to move it underground. However, the compact design forced Nod technicians to discard all but the lightest armour plating, rendering it vulnerable to all anti-tank weaponry. They also have a penalty of unable to hit targets in higher plane or the ones that are somewhat protected by walls, as "Flame can't climb". The vehicle also can be stopped by the enemy player placing concrete in and around their base so they can't dig though.
The Devil's Tongue is fast and its twin side-mounted flamethrowers are highly effective against enemy structures and infantry. Its tunneling abilities prove to be indispensable assets to the Brotherhood's war effort, capable of ambushing enemy infantry and burning structures. However it cannot hide itself from deployed Mobile Sensor Arrays once the tank enters its radius. Any tank or aircraft would able to deny them outright. EMP also can force this fire mole to surface in dry land.
