The 1st Infantry Division’s 2nd Armored Brigade Combat Team will begin a major combined arms live fire exercise ( CALFEX ) this week that will continue through late October. Periods of significant noise may be heard and felt throughout the Flint Hills region during the training.

Community members can expect significant noise on Sept, 13, 16-21, Sept. 30 – Oct. 4, Oct. 7-10 and 15-18. Those dates are approximate since training needs, operations and weather can shift schedules. Significant training noise may occur throughout the day and night.
