At 6 o’clock on the morning of March 27, 74 candidates began the last event of the USAREUR EFMB, a 12 mile ruck march in three hour or less. The ruck march event requires that candidates wear a loaded ruck sack for 12 miles while carrying their individually assigned rifle and a CBRN protective mask. Candidates were allowed one service member from their chain of command to pace them during the exhausting ruck march.
