CPT Sarah Cudd from Public Health Command, Fort Knox is only 1 of the 46 candidates who earned the EFMB yesterday at Fort Dix, NJ..27 April 2015.This is her last few seconds of the 12 Mile Foot March. The Foot March is the last event of the Expert Field Medical Badge (EFMB), and must be completed within 3 hours.If you want it, you have to go get it. Watch this video. This EFMB candidate wanted it, and she got it. It took heart, guts, determination, falling down and getting up, and a little motivation from the crowd to get across the finish line.
