The Ultimate Marine Corps Challenge

At 5 a.m. when most college student's are still asleep or just getting in for the night, the Auburn University Marine Corps are pushing their way through morning training.

After running 4.5 miles with more than 10 pounds of gear, jumping over walls, crawling through mud pits and pulling up sky-high ropes, it's hard to imaging how the AU Marine's are able to make it to class...and stay awake.

Eagle Eye reporter, Carrie Williams, joins the Marines for their 5 a.m. training and get's put to the test in the Ultimate Marine Corps Challenge. Watch here for the full story.
