If they have the speed very good for 2 things.
1) advance scouts
Move to an area of woods & park on edge with an exit route, turn range down low so it does not fire. If its small & stationary should be safe from view at over a KM great on larger maps.
2)ambush
set up behind something or in woods to surprise as player is lax not expecting an attack this early because your tanks can't be there, so he is often moving flat out.
Again an exit route is needed do not get involved in a punch up but this can slow him down enough to let you take the good ground.
