You know how the NF Heavy tanks have the sharp pointy things on the front? Well, I think they look like a mine sweeper attachment....and I think it'd be cool if that was the actual function of that...make it an add on for the tank, and make it so it can defuse mines it touches?
Grenadiers in a tank don't need to worry much about mines unless they don't have mine defusal. So I guess you could become a grenadier and 'pretend' it's a minesweeper...
Strap some scouts to the front of tanks instead Tell them you're taking them to an uber sniping spot, and when they get blown up just shrug your shoulders.
