Exactly. This sort of thing did exist within the Frontier Army, although in a very rough and undocumented form. The majority of the Army's interactions with Indians were of a peaceful nature, as opposed to combat operations. Some commanders (typically at the company level but sometimes at regimental level) did come out with more or less official guidance, but that was rare.

It should be mentioned, though, that the Frontier Army had a huge experience and knowledge pool to draw from. We're only now starting to create that.
