Engineers from the 105th Engineer Battalion assemble on the range to deploy their first charge of the day at Fort Bragg, N.C., Feb. 7, 2015. This confidence-building charge, built from C4, is meant to create a large explosion in order to build enthusiasm to prepare the soldiers for the rest of the training day.
