 In a combat zone, incidents can be random or unpredictable. That's why soldiers with the 539 military police detachment, stationed in Bagram Air Full Afghanistan, take on the responsibility to keep everyone safe day or night. These guys don't sleep. They'll try to get us any time of the day and we've got to stay one step ahead of them. They've only got to be right once. We have to be right every time. Sergeant Douglas McIntosh believes his role as an MP is to keep everyone protected. Do you know how fast you're going? Do you have a speed limit? Speedometer? Bagram Airfield is like a small city with more than 20,000 military members and civilians. This is why soldiers like Specialist Judy Sanchez say traffic control points are necessary to help avoid accidents from happening. Pedestrians are just walking out when the cars are coming by and they're not paying attention and we've actually had people get hit and also to control the traffic flow since Bagram is pretty big it actually affects the whole fob not just here on Disney so we're trying to look out for the safety of everyone. Sergeant First Class Jason Pretz says his team understands why safety needs to be the number one goal before they begin their shift. As for any soldier in a deployed environment each day has its own challenges. Each day is unique than the day before. Our soldiers embrace that, they strive forward with their head up asking what more can I do to accomplish this mission and to just help out.
