The Marines are in the area conducting live-fire artillery training on Fort Bragg's ranges, a Fort Bragg Facebook post states. A Fort Bragg garrison spokesman said the Marines will train here through the end of April. According to the Facebook post, there will be no mass firing from 11 p.m. to 5 a.m. daily or 10 a.m. to noon Sundays.
