Near the finish line, Cudd is visibly drained – resting on her hands and feet. Her fellow soldiers try desperately to encourage her up. Fifty feet from the finish line, she uses her rifle to pull herself to her feet. She walks a few more feet, and then falls to the ground again.

Finally, she rises to her feet and finishes the race. She is one of just 20 percent of the soldiers who finished April 27 in Fort Dix, N.J. The Post reports that she earned her badge.
