Marine Raider Memorial March participants do a set of pushups around the monument honoring 15 Marines and a U.S. Navy corpsman who died in a 2017 plane crash near Itta Bena, Miss., Saturday, July 14, 2018. The group of 30 former comrades and widows of members of Marine 2nd Raider Battalion, will have teams that will be on the road around the clock through July 27, relaying rucksacks of dirt and sand from the crash site and memorial site over 900 miles to Camp Lejeune, North Carolina.
