To get super-fast troops, select 1 mine-tank and 5 grunts. Put 
them into a team and then press the 'F' key to put them into 
formation and HEY PRESTO your troops now move as fast as the the 
mine tank.
(This cheat also works with 1 mine tank and 5 submarines, wich 
all travel at the same speed as the mine tank.)
