- One FATIGUE is gained after a Movement activation if it was preceded by a Movement Activation or a Shooting Activation this turn, i.e. the first Movement or Shooting activation of the turn does not generate FATIGUE, but any subsquent Movement activation generates one FATIGUE. If the Movement has been used to engage melee, the FATIGUE is gained immediately after the movement, but before the melee is resolved. If the Movement is followed by a shooting (as with javelins) the FATIGUE is gained immediately after the Movement, and before resolving the ensuing shooting.
