General tips: Don't rush into death and destruction. Often,
enemy soldiers will come to you regardless of
what the scenario is. If there is no turn limit,
moving up very slowly usually pays off big-time.
Bring a mule. Every battle has some nice goodies
lying around, so equip a couple of your worst
troops with minimal equipment and use them to
scavenge.
High explosives are your friend. When in doubt,
blow up the enemy real good using grenades,
bazookas, and satchel charges placed against walls.
