Cannon/Home Village

"Cannons are great for point defense. Upgrade cannons to increase their firepower, but beware that your defensive turrets cannot shoot while being upgraded!"

Summary
Cannons are the first defensive structures that players receive. They are both cheap and quick to upgrade until they get to a higher level.

Defensive
Cannons have a high rate of fire and good range, which makes them an ideal deterrent for wall breakers. Cannons are also useful for keeping giants from getting to the other defenses. Defend mortars and wizard towers by placing them within range of the cannons. Make sure cannons are placed within range of the anti air defense, as they are unable to target air units.

Offensive
Cannons are unable to target air units. This makes them easy pickings for balloons or dragons if they are not within range of anti air defenses  Cannons are also only able to damage one unit at a time. This makes it very easy to overwhelm them with large groups of archers or barbarians.

Trivia

 * Cannons undergo dramatic visual changes at levels 7, 10, and 11.
