Artillery allows you to call down explosive strikes on enemy positions before or during the battle for each island. You can target enemy structures and areas that could present an obstacle for your troops. The explosions also cause splash damage, so firing at objects close-together is often a good course of action. It has a damage radius of 0.49, meaning is affects units that are 1.5 tiles away.
First Shot: 3 Energy
Second Shot: 5 Energy
Third Shot: 7 Energy
Fourth Shot: 9 Energy
This is a perfect piece of equipment for picking out a target that is potentially a great threat to your troops, and eliminating it. You are usually able to take out one Building with the Artillery's multiple shots, and, if you don't, it should at least be sufficiently weak for your troops to take it out with ease.
It's up to you whether you think the best tactic is to take out one defensive structure, or weaken two (or more), but usually it's better to only be getting fired on from one angle at a time, so our preference is to concentrate on the biggest threat, and use whatever Energy is left on the next structure.
Remember, you can actually damage multiple buildings with a single Artillery strike. If the enemy has Mines close together, or buildings, you can damage more than one a time with a well placed shot.
Finally, you can target weak buildings and supplies to attempt to regain more Energy than you expend with your shot - if you take out multiple supplies, for example, you will sometimes be able to afford another shot.
