“Four Army units at Joint Base Lewis-McChord are scheduled to conduct artillery training over the next two weeks, which means it might be noisier than usual around the installation.
The first training window begins at 6:30 a.m. Monday, and continues until 9:30 p.m. Friday, JBLM officials reported.
The second window is from 10 p.m. April 4 to 7 a.m. April 5,” by Adam Lynn, The Olympian.
