Funeral services for Lance Corporal Jacob Hug took place at Christ's Church of the Valley in north Scottsdale.
22-year-old Hug was a combat videographer based in Japan.
He was on an aid mission in Nepal following the deadly earthquake that happened in April when his chopper went down.
Six US Marines and two Nepalese soldiers were killed.
Hug and his fellow Marines who were killed were honored with a ceremony at Camp Pendleton, near San Diego, on Wednesday afternoon.
Hug was a highly decorated Marine.
His uncle spoke at the service on Thursday saying Hug had it in his heart to be a Marine and there was no talking him out of it.
"I am so honored of his service. They knew it was dangerous, anybody that is familiar with helicopters, flying them at that altitude and those conditions is dangerous, and Jacob knew that. That is the epitome of bravery, is doing action in spite of the fear," said Hug's uncle.
Hug would have been stationed there when he was scheduled to return to the states in July.
The cause of the crash remains under investigation.
