Is there actually a way to get those Hueys to Brunei?
Yes, but it is not intuitive and has risk. One of the SH-70s on the Newcastle can deploy to either the Westralia or the Stancliffe. The Huey will then be able to park on the Newcastle and switch later.
It does give the added benefit of an ASW Heli (without reloads) either on the independent Westralia or really beefing up the main convoy with the best heli you have. The SH-70 also has the best legs
thanks for your points, I'll fix and get out an update. Really not sure about the convoy, it did seem to work for me. Perhaps the Ocean Tug is the problem... I'll get rid of him.
