My "retirement" job in LE is for a tribal police department. I patrol a river and adjacent lands and keep trespassers off. From time to time I arrest someone (indian or otherwise) and they go to the relevant court. I get along with both sides, and I remember who the best fighters in VN that I found myself with-thats right native americans. Many had more guts than brains IMHO, but as fighters they got my vote. I even found some in the 1/7 Cav-Custers old outfit. When I landed to pick WIA/KIA, I could always count on them (and many others) for protective fire even if it exposed them.
I will always remember a member of the Seminole tribe I picked up-he had his left arm gone below the elbow, he fired his M16 till it was empty, then thumb cocked his 45 and fired it till it was dry, me and my crew all signed for him to get a Silver Star, never heard what happened though.
Yeah I have met a bunch of AH indians, but the ones I have made friends with are friends for life-mine or theirs.
