Getting units to move upon trigger activation

[Szadowsz 10]

I was just wondering how to rig it up so that when an area is clear, a helicopter will turn up with reinforcements.

i have the heli set to hold position until a trigger is activated.

I figured I should use a switch trigger synched to the heli or something, but Im not exactly sure how and what needs to be synched.

Synch the "area clear" trigger with the hold waypoint.

awesome explains why me and friend couldn't make it work properly we synched the move waypoint instead
