FORT MCCOY, Wis. — Before the sun crested the horizon this morning, 22 Wisconsin Army National Guard Soldiers began a grueling three-day gauntlet known as the Best Warrior Competition. The demanding competition pits Soldiers from across the state against each other as well as the limits of their own endurance, taking the measure not only of their physical fitness but their skills in land navigation, Soldier tasks, military bearing and composure.
