Survival techniques make up a set of emergency practices that, understood, trained and applied in extreme situations, allow the individual to prolong his life and remain physically intact, allowing him to rescue or find a way out of the problems.
Extreme disaster situations (accidents with means of transportation, earthquakes, shipwrecks, etc.) can put the individual away from civilized life and relief; knowledge of survival techniques can save his own life and that of others in his company. Survival training is one of the military disciplines.
