Every time a USMC unit is attacked it will fatigue. The level of fatigue is reflected with the fatigue marker. Like a battery, the more fatigue a unit has the less effective it will become, and it will suffer penalties when it attacks the enemy. Units start off with no fatigue and have a maximum of 10 fatigue points.
Potentially a USMC unit could lose several fatigue steps in a day from being attacked by the Japanese in Movement, Japanese Combat and Night Phases.
To recover fatigue a unit must be in Command range and not adjacent to an enemy unit. It will recover 1 fatigue point per turn.
