I was motivated to read Black Cat 2-1 because I helped restore a Huey Gunship that served in the Black Cats (actually the guns were Alley Cats, but same unit). Author was a commissioned officer so there is a retelling about his fleet up to company commander, dealing with infantry seniors, and the relationship with the warrants. Also a real good recounting of the base nearly being over run with enemy inside the wire. This is where I first learned slick ACs flew in the left seat of Hueys because it had a better view out the chin bubble.
