It is worth halting here to stress that Miklos is no Yankee Doodle Dandy. Morgan's Rifles can face the fire of the excellent German J eger. BUT remember 8.2.2 which doubles movement on roads or tracks. ZOCs are locking and in the case of rifle ZOCs cost extra to enter. There are limitations to American movement depending on the commander.
Fire consists of referencing SPs firing against range to hit the target.
Dicing on separate tables for rifle and artillery fire then inflicts the damage. Rifles also have the ability to cause an Army Morale Loss if they start winging enough of the officers. If the British can employ their cannons skilfully they can batter an American line into either retreating or attacking. The American guns are immobile in their Bemis Heights entrenchments. You work out the odds, pick your lead unit and play a tactics chit.
