Even though they wont be doing the CFA again, they will be constantly physically tested, and expected to maintain a high level of fitness. The Army is much more about fitness than the other branches. USAFA marchback from Jack's Valley for example is a 5 mile hike with a camelback. USMA marchback is a 12 mile ruck from Camp Buckner with a full pack and rifle. Throughout the year, they will be doing ACFTs, IOTC, Crucible, Rucks, PT, etc. And depending on the club, fitness and grit are a deciding factor in the tryout. Clubs like Combat Weapons Team, Parachute, Sandhurst Black/Gold and even Scuba, the PT portion is the first part of the tryout, and weeds out a good portion. A physical fitness mindset is important and your cadet candidate needs to make sure they work at it.
