US Army military police soldiers are responsible for protecting Army posts by guarding gates, controlling traffic, and responding to emergencies. They also oversee military prisons and detention centers that house uniformed criminals, like the US Disciplinary Barracks at Fort Leavenworth, Kansas.

Business Insider spent four days at Fort Leonard Wood in Missouri to see how 31 Bravos and 31 Echos spend 10 weeks training to become military police and detention specialists.
