This used to be published as "Survival, Evasion, and Escape" with the same field manual number. I have an old printed copy dated 1969 which includes the missing Evasion and Escape sections.
That sounds suspiciously similar to the SERE course the military does: "Survival, Evasion, Resistance, and Escape". "Resistance" entails resisting torture without divulging secrets to the enemy; in SERE training they will actually put you into stress positions and waterboard you, which is where they got the idea to do that kind of thing to prisoners.
