When playing against the computer, enemy units will
always come toward you. To win nearly any scenario,
hunker down and set up a defensive zone.
Remember that it's just as effective to break the
enemy's morale as it is to kill him; suppression can
be just as effective as direct hits, so don't be
afraid to fire at an area rather than a unit.
Putting a tank just behind the crest of a hill will
give it the 'hull down' advantage; this way, its
turret can see over the hill to fire at targets, but
its hull is shielded from attacks.
