The rules were originally written at Rogers Island in the Hudson River near Fort Edward.
The rules were the result of Rogers' blend of Native American tactics and his own innovative combat techniques, ideas that were considered revolutionary by military standards of the time.
Combined with intensive training and live fire exercises, these rules created a mobile, well trained force that was capable of living off the land around it in order to sustain itself for long periods of time.
As Rogers personally selected volunteers to form the first company of Rangers, he wrote a Plan of Discipline containing 28 guidelines that he found useful from experience.
[1] The 75th Ranger Regiment formally adopted these rules, along with Rogers' 1757 Standing Orders, in the 1950s.
