What should I expect in civil affairs selection?

You can expect a lot of testing. They want to see your physical limits, how your intellect works, and how you can work with others, both team work and as a professional. It changes frequently to keep up with their needs, especially as they evolve as an organization. Doing a search of this site you will find some examples, but be aware, no one should be telling you exactly what they went through, it's confidential. I provided consistency throughout. I was never first or last in the rucks/runs. I was flexible in my reasoning and thought process. I did give the best I had and followed instructions exactly. I was selected.
