A note on Hold waypoints: Group moves to the waypoint and holds until the enemy is spotted where they then engage until the threat is eliminated OR no longer known. They then return to the hold position until more enemy has been spotted. To break a hold waypoint, a switch trigger can be implemented. Hold waypoints never complete (anything put into a HOLD waypoint's activation field will never be executed!). Timeouts also are ignored.
A note on Guard waypoints: Group moves to the waypoint and holds position. When the enemy is spotted, the group will behave as if it were a Hold waypoint (see above). When Guarded by side triggers are placed on the map, groups at guard waypoints will move to the guarded by side trigger upon reaching their guard waypoint. If more than one guarded by side trigger is placed, the group will defend the highest priority trigger (The first trigger placed) If more than one group has guard waypoints, the groups move to any unoccupied guarded by side triggers until all are occupied. Once all triggers are defended by a group, any groups remaining with guard waypoints will hold at their guard waypoint until a guarded by side trigger is no longer defended. When the enemy is spotted anywhere on the map, the group at the lowest priority trigger responds and any groups waiting at guard waypoints will move to fill their spot. Timeouts and conditions in guard waypoints are ignored and the waypoint never completes.
