One of the first things you learn when you join the military is that you are always wearing the uniform. 

For the uninitiated, it could seem a little unfair. But for those who have taken the oath, always being in uniform isn’t a burden; it’s an honor. When you’re in the military, you share in the responsibility to keep our communities safe, to protect innocent Americans, and to use your training to come to the aid of those in need. 

It doesn’t matter if you’re a salty Navy SEAL or a slick-sleeved private. It doesn’t matter if you’re stopping by the post office to check your mail, getting in some extra reps at the gym, or — as in the case of Sgt. Samuel Kosgei — out shopping with your family. 

On September 18th. Sgt. Kosgei was out with his family at a Walmart in Colorado Springs, Co when he heard screams. Without hesitation, Sgt. Kosgei told his family to stay put and he ran towards the commotion.
