I doubt she would have gone this far if that were true.
Knowing the military, it is just as likely than not that she was out of shape but was supported for a program they all “knew” she has no business trying to enter but couldn’t just write her out of the program, after all, political correctness trumps qualifications every time so I am sure she received dedicated conditioning and support that a male candidate would never be given.
100% true. Look at her picture on the first day. No way she could make it. The same thing happen to the first woman to go to West Point. She fought and fought to get in and then quite days afterward. She was so out of shape.
