What are some basic survival skills everyone should know?

So when I was at my first unit, my sergeant in charge of our section was not the best runner but needed to pass his pt test to go to a school to become a sergeant because, at the time, he was still a specialist. Anyways, you can ask someone to run with you to pace you, and I was in the best shape at the beginning of my enlistment. So I helped him barely make it to the cut-off time, and I could tell he was having a hard time throughout the run, but in the end, it made me feel good to help him.
