@Advocate A typical game usually consists of 10 to 20 miniatures per side. Figures act individually, each able to undertake 2 actions per turn. These actions could be moving, firing, reloading, taking cover, or a few others.
Soldiers that are wounded can only do 1 action per turn, so for example firing and reloading a musket takes twice as long, and a wounded man can't run, only walk/limp
Officers and Maori Ariki (Chiefs) can issue orders, sacrificing their own actions to allow another to act. An officer could order a wounded man to fire faster, allowing him to get an extra action. No soldier can ever exceed more than 3 actions per turn however.
Militia can end up wasting an officers time (and actions) as they can fail to take orders. These orders can only be given to units within 12", so encourages players to keep their leaders close by.
As for morale, if man is wounded he must immediately make a morale check, and may be forced to fall back. Officers and Ariki can attempt to rally soldiers within range, bringing them back into the fight. Militia, due to their poor training, must take a morale check every time they are fired at, regardless if they were wounded or not.
