The latest version of the "stranded behind enemy lines" manual included in the survival kits of all branches of the U.S. military. A distillation of the information contained in the survival "bible," the USAF's enormous tome on Survival Training, AFR 64-4 and updated from the previous version which contained a significant amount of outmoded information. Now a multiservice publication used by all branches of the U.S. military (FM 21-76-1, MCRP 3-02H, NWP 3-50.3, AFTTP(I) 3-2-2.6).
