Watch this guard at the Tomb of the Unknowns get stabbed and carry on

Imagine being at your regular guard shift and your relief commander comes in and accidentally stabs you in the foot. Most of us would have trouble walking and go to the hospital. We certainly wouldn't finish our shift.

But we aren't The Old Guard.

A video taken by a visitor to the Tomb of the Unknowns at Arlington National Cemetery captured a bayonet mishap – the last thing anyone wants to hear after the word "bayonet."

The Old Guard – soldiers from the U.S. Army's 3rd Infantry guard the Tomb of the Unknowns 24 hours a day, seven days a week, in any weather and even the middle of a hurricane.

Every half hour, the guard, called a Tomb Guard Sentinel, is changed. the changing begins with a white glove inspection of the outgoing guard's rifle.

A video captured by YouTube user H Helman shows the Tomb Guard Commander accidentally losing his grip on the rifle and putting the bayonet through the guard's foot.

he look on the guard's face never changes. There's clearly a shock to the system as the bayonet slides home, but all you ever see from the guard is a very slight wince.

The Old Guard is trained and drilled meticulously to maintain their professionalism, military bearing, and discipline. Accidents and outbursts from the Sentinels are extremely rare. As a matter of fact, if you weren't watching this incident closely, you may even miss what happened.

Instead of running away, being carted off, or even being relieved, the Sentinel who was stabbed carried on with his shift. He marched back and forth along his route, blood oozing from his foot as he walked.

Neither he, the commander, nor the other Sentinels ever missed a beat. They sharply finished their watch. This kind of discipline is the reason 90 percent of the soldiers who try to guard the Tomb of the Unknowns wash out of training.
