These Marines train with shock and pepper spray in their eyes.

Unsurprisingly, military training is heavy and often drives people to their limit of endurance and pain, but even knowing some training methods can be quite shocking to those who are not part of this reality.

The video above, released by the Daily Mail, shows US Marines going through really heavy tests. First, they receive generous spray of pepper spray on their eyes, and then they are ordered to keep their eyes open and follow up on the task of applying a few blows. Obviously, the Marines complain a lot about the burning and the pain - one of them says he feels as if he is being needled in the eyeball.

In addition to this test, they go through a crash session, which they continue to receive even when they are screaming and lying on the floor. According to Sergeant Paul Delekto, this training is level one of the preparation of the Marines.

According to the sergeant, this evidence makes the Marines better prepared for situations involving intoxication and shock, learning to deal better with the pain and reactions of the body itself. So, would you face this kind of test?
