Artillery
There is already a mod for artillery strike but I want it to be regularized. Basically, people can get a cannon (or other artillery) instead of 10 troops (or pay gold)(value changeable by settings). The cannon acts as 3 (changeable with settings) troops. When defending, the cannon will die last [except for commander] (3 other troops die instead of cannon, if possible. and if 3 would die when there is a cannon and 1 troop, only the troop dies. On offense, cannons can fire between 2-4 (changeable with settings) spaces away. Its attacks happen before troops. Cannons cannot be killed while attacking.
