The lockdown at the base, about 50 miles southeast of Boise, started at 4 a.m. Wednesday and ended at about 6 a.m. after getting the all clear, according to the Washington Post.
Officials did not explain what led to the false report of shots fired.
On Tuesday morning the 366th Fighter Wing began conducting a four-day, 24-hour training event “to prepare for real world contingenies,” according to a separate post on the base Facebook page. “Mountain Home residents may hear an increase in noise from the base throughout the week due to the exercise.”
But it was unclear if the false report was in any way related to the noise increase.
