"Aldama described a tattoo on his calf as a skull with a rifle and a military-style helmet with flames surrounding it. On the helmet are the letters “C P T” for Compton."
So at some point "military-style" was switched to nazi. I don't know why, but since there's apparent conflict let's do our own research. Googling Nazi helmet gave me plenty of images, and they generally have a large flare on the back and the brim turns up. The helmets also seem to typically have badges on the side and I didn't see any that had a band on them like in the tattoo. I think these helmets look far more like the type worn by US troops in the Vietnam war.

That is obviously a much larger set of people than closet Nazi admirers, even in the U.S.
And the previous poster might be an European from a country once occupied by Nazis, or even Germany, where such knowledge is part of the historic memory.
Most Czechs with at least elementary history knowledge could distinguish Nazi helmets from other ones at first sight; the Stahlhelm is a very distinct design and it is part of a very dark memory for us. It had some innocent uses too (Austrian firefighters or Chilean cavalry, IIRC), but it is tainted here forever.
