Survival, Evasion, Resistance and Escape is a common school of thought for military service members in high risk positions. That’s why the military developed SERE training. The purpose of the school is to put Soldiers, Marines, Sailors, and Airmen through the worst possible scenarios in the event they find themselves deep behind enemy lines with absolutely zero support, or even worse, captured by the enemy.
The most common people to go through this training are pilots, and special operations troops, as they are at the highest risk of finding themselves in a situation where they may need to conduct a SERE operation. With that said though, it is not uncommon for regular troops to go through the training if they are attached to one of these units, or if their unit may be placed into a position where this type of operation could be required.
Here is a short video released by the people who conduct the SERE training as instructors.
