Fourteen Marine Raiders are getting ready to step off one month from today on a 770-mile ruck march to commemorate their fallen brothers on the one-year anniversary of a Black Hawk crash that killed 11 troops off the coast of Florida.

On March 11, the group, Marine Raider Memorial March, will depart the crash site at Navarre, Florida, on the 11-day, round-the-clock operation to the Raiders’ home at Camp Lejeune, North Carolina, delivering the only surviving piece of equipment from the crash: a paddle belonging to one of the fallen Raiders.

Staff Sgt. Nate Harris, a critical skills operator who began organizing the march the day after the crash, said the undertaking will honor the families of the fallen.

“I wanted to do something to give back to the families,” he said. “There’s never enough we can do for the families; we have to show them how much these men and their families mean to us.”
