In the game's words

How to use it

The Heavy Cannon is a long-ranged artillery piece that does a lot of area-of-effect damage. It is slow like other cannon and vulnerable once units can get close enough to attack it. The Heavy Cannon is only available from the Factory or the Home City. It cannot be conventionally trained like other military. British and Ottomans lack the Heavy Cannon, but have unique artillery instead.

History

The logistics of moving, maintaining, positioning, aiming, and firing artillery required a highly drilled and disciplined team with a sharp commander. In addition to the men and artillery pieces in his command, an artillery officer had to see to the horses used to haul the pieces around - sometimes up to six for heavier guns. When one side in a battle could field hundreds of artillery pieces, the logistics of just moving them into position were taxing. "Heavy Cannon" is a relative term, but in general, cannon considered 'heavy' were typically used as permanent gun emplacements to defend Forts and strategic locations.
