Yes. http://www.military.com/join-armed-forces/air-force-bmt-boot... How much of that is really necessary to be in IT security though? I'm sure it makes you a better person, but when you have highly skilled individuals and show them that kind of requirement, the majority of them would rather stay in the private sector.

The exception is if you have a specialized degree there is officers school for the branches, but basic training is still required, you will still be marching and be broken in, but after that will be more classrooms than physical activities.

Pilots especially must be physically fit. I've heard that leg strength is especially important so that you don't pass out at high g-forces. Drone pilots probably not so much, obviously.

The Reserve forces might be slightly less rigorous, but I'm not positive.

The cyber warfare stuff is mostly Army and Navy though as far as I know.

Agencies like the DHS are the ones that are really struggling to find IT talent. They have a huge amount of responsibility (security all non-military government infrastructure) and have a bad reputation currently (because of airport security staff).
