Narrative:

Upon being cleared onto the departure runway to 'line up and wait' we began assessing the traffic situation and became aware of traffic landing. We watched the gulfstream land; and listened to several helicopter traffic get clearance to land on the ramp 'at their own risk.' being unfamiliar with the ZZZ helicopter procedures; the clearance meant only that helicopter traffic was in the area. We received takeoff clearance and departed. Upon rotation; I noticed a white landing light/green position light on the runway centerline within a mile of our position. At the same moment; the tower controller was urgently stating to a marine UH1 they 'needed to stay north of the runways.' our TCAS showed traffic directly ahead; 200 feet above as we were leaving the runway. I increased the rate of climb and turned 15-20 degrees to the south in an effort to avoid a collision. The TCAS reported traffic; as the helicopter went by the right side of our aircraft 200 feet below according to our TCAS readout. Once clear of the conflict we contacted departure controller and continued without incident to our destination.tower controller issued a clearance to a military helicopter pilot who is obviously unfamiliar with the normal field procedures. The controller is obviously used to issuing helicopter landing clearances to local helicopter tour; etc. Traffic allowing the controller to focus on aircraft traffic departures and arrivals. Special attention needs to be paid to obviously unfamiliar military traffic.
