survival and evasion tips

i'm reading a field guide put out by the US Army in 1969 called "Survival, Evasion & Escape" full of tips for soldiers who found themselves trying to survive behind enemy lines. here's a couple things i picked up:

• when dealing with natives, leave a good impression. other men may need this help
• if caught in an avalanche, use swimming motions to stay on top
• take care when crossing thin ice. distribute your weight by lying flat and crawling
