A convoy of vehicles (boats, cars, whatever) that has the goods carry-ing merchant ships in the centre, in as close to a circle shape as possible, while the battlecruisers surround the outside. Should they be fired upon, the more expendable battlecruisers will take the damage, and not hit their own firing from the closest range of all. This shape also means that less "armour" is needed to surround the good ships.
An armed convoy is heading our way, there is an opening at the front, lay a few mines for them. We should hit the goods.
