 The expert field medical badge, also known as EFMB, is one of the toughest badges in the Army to obtain. There's a high failure rate because the testing is difficult. One of the first things a candidate must do before they can even begin the combat testing lanes is to successfully pass the day and night land navigation portion. If they don't pass, they go home. Does everybody have a test sheet? Candidates must negotiate the lane-up course without any assistance from cadre or other EFMB candidates. Candidates must locate three out of four points given during day, three out of four points given during night to receive a go. The land navigation examination alone will send a majority of these EFMB hopefuls home. Whether it's plotting points incorrectly, losing track of their pace count, or simply just getting lost. After finding their points, they will head in and turn in their scorecard and await their verdict. In Fort Campbell, Kentucky, it's our first class Jadal Samara.
