Watch Captain Sarah Cudd's final steps of an intense twelve mile march at Fort Dix, New Jersey.  The captain can barely walk, but she doesn't stop until she completes her mission.  The task was part of the requirements of the Expert Field Medical Badge.  Cudd was one of forty six candidates who completed the march.

The march was not the only requirement to earn the EFMB according to news.com.au  'Personnel not only undergo the march but a comprehensive written test, weapons test, army physical fitness test, navigation courses, obstacle courses, as well as have their radio and survival skills tested and their medical skills tested.'

Cudd's efforts have been viewed by over 1.2 million folks on Facebook.  She truly is an inspiration.
