In this episode, John Spencer is joined by Staff Sgt. Nicholas Garner, an instructor for the Urban Mobility Breacher Course, which is a part of the US Army Engineer School. As a tactical task, breaching can be challenging. That becomes especially true in the unique conditions of dense urban terrain. Staff Sgt. Garner explains how the course trains soldiers to understand and overcome those challenges, and the importance of having urban breaching capabilities in units.
