A Marine funeral is one of the most chilling and patriotic sights to behold. Friends, families and fellow servicemen gather to pay tribute to an individual who dedicated his or her life to protecting the freedoms of this great country. And when that individual is finally laid to rest, he or she is carried to a final resting place by a highly trained, select group of Marines who deliver a breathtaking performance to properly honor their fellow patriot.

A video from the United States Marine Corps offers a glimpse at the specialized training of these men, and showcases what it’s like to be part of the most elite unit in the military. “A lot of people don’t really know what we do or don’t really know what it entails,” says Lance Cpl. Ja men Miller in the video. “And when they find out, they’re taken back a little bit.”

Miller is one of just 15 body bearers in the Marines whose job consists of bearing the casket of those who served. The specialized group of men train multiple times a day in order to perform flawlessly for each and every funeral they are apart of.

In the year that Miller has been a body bearer, he has already laid to rest nearly 200 Marines. “It’s our job to have flawless bearing and to perform our job at the max, at 100 percent for them,” Miller explains. “We don’t do it thinking about ourselves. It’s all for the family and for that American hero.”
