It was black, and if you have ever heard a blackhawk, there is no mistaking it for a civilian chopper. It has a mean thump to it (I grew up on base LOL).
Well, my comment was referring to the conspirasah type of Black Helicopter popular in the late 90's. If it was actually painted black, as opposed to the dark OG CARC used by the Army, it very well may have belonged to Customs.
