"Don't mess with Marines"...

A U.S. Marine Corps veteran was standing in a gas station on Wednesday when he single-handedly disarmed a robber. 

The Yuma County Sheriff's Office said the incident happened around 0430 local time at a Chevron gas station in Yuma County, Arizona. 

Sheriffs posted a video on Facebook of the stunning firearm disarmament by the combat veteran who was able to take control of the situation in a matter of seconds. The video shows the veteran was well aware of his surroundings when the gun-wielding juvenile attempted to rob the store. 

Marines and other service members are taught firearm disarming techniques. Here are a few steps via an old US Army training manual of how to take down an armed attacker. 

The most crucial part is that the former Marine was well aware of his surroundings and had proper training. If this was anyone else, the situation could've turned very ugly.
