A Cannon is an item used in Mobilising Armies. It can be placed anywhere facing north, south, east and west and will automatically fire in that direction. Whilst it will hit squads in its line of fire, it doesn't do as much damage as a Glider and can hit and damage your units too! It should therefore be placed carefully. It is cheaper than such scrolls as the glider and therefore many poorer players use them however richer player tend to opt for the glider because of its precision, high hits and ability not to damage your units. It hits damage of around 500-1000 normally and fires once. The Cannon costs 300 investment points. It is deleted from your inventory after it has been used. And even though it damages your units, it is good to use along with your gliders so they wont know which one to try to block first.
