FM 21-22: Survival at Sea
Field manual 21-22 covers shipboard safety measures and equipment, abandon-ship procedure, operation and navigation of lifesaving craft, measures for sustaining life while adrift, rescue procedure, and brief suggestions for instructors. Since a landfall may prove only temporary refuge, some hints on survival ashore are also given. Swimming and lifesaving techniques, treated in detail in FM 21-20, are described only briefly in this manual.
