The soldier from 3rd Brigade Combat Team, 10th Mountain Division, was shot accidentally while going through Expert Infantryman Badge (EIB) testing at 2 p.m. Oct. 26, 2018, according to Kim Reischling, a spokeswoman for Fort Polk.
The Army did not release the soldier’s name, but Reischling said he is in stable condition.
Infantry soldiers participate in testing each year to show they have mastered their core infantry skills and to earn the EIB, a distinctive badge consisting of a silver musket on a blue field.
Expert Infantryman Badge candidates wait at the start of the 12-mile foot march before the sun rises, April 3, 2014.
The testing requires soldiers to pass a day-and-night land navigation course; complete a 12-mile road march with their weapon, individual equipment and a 35-pound rucksack within three hours; and pass several individual tests involving weapons, first aid and patrolling techniques.
Soldiers are required to have their weapons with them during EIB testing, but there “shouldn’t have been live rounds” present when the soldier was shot, Reischling said.
The incident remains under investigation, she said.
