21st Century Toys released several great 1/6th scale Sherman Tanks back int he heyday of the 1/6 military craze. The tanks were Radio Controlled. Very late in the game, they released a 1/8th scale (close enough) M1 Abrams tank, also Radio Controlled. My tank's RC capability never worked. Oh well.
It was still fun to put that thing up with infantry running alongside it.
