I love Prairie Fire! My thanks and congrats to the Dev Team! I thought it was a damn shame that vanilla ARMA AI can't navigate all those beautiful rivers and the Mekong Delta, so I developed a script that solves this problem. Using the editor you can place boat Move waypoints and a call to my script in first move wp, and the AI will then navigate the windiest river. Note that each waypoint must be visible and unobstructed from the last waypoint (as AI is not actually path finding).
This means VC boat patrols, boat QRF teams, AI boat transport, etc., are now all possible on rivers!
