Deadliest Sniper in Marine Corps history, Charles ‘Chuck’ Mawhinney, dies at 75

The US Marine Corps deadliest sniper, Charles “Chuck” Mawhinney, who went nearly two decades avoiding any recognition for his kill record until he was ousted in a book, has died.

Mawhinney died at his home in Baker City, Oregon, on Feb. 12, The Baker City Herald reported.

He was 75.

Born in Lakeview, Oregon, Mawhinney began his legendary career in 1967 after he graduated from high school and enlisted in the US Marine Corps that same year to fight in Vietnam.

Upon joining the branch, he attended Scout Sniper School at Camp Pendleton and, following his graduation in April 1968, received orders to South Vietnam on a 16-month rotation, according to the US Marine Corps.

From 1968 to 1969, Mawhinney — still only a teenager — was credited with 103 confirmed kills.

An additional 216 kills were listed as “probable” since the enemy’s bodies were risky to verify in the active warzone.

Mawhinney had confirmed kills over 1,000 yards, with the average kill shot for snipers during the Vietnam War taken at a distance of 300 to 800 yards.

He received a Bronze Star Medal with Combat Valor, Navy Achievement Medal, Navy Commendation Medal with Combat Valor, and two Purple Hearts.

Despite having the highest kill count out of any sniper in the branch’s history, Mawhinney returned home in 1970, slipped back into everyday life without recognition, and secured a job with the US Forest Service.

For years, it was believed that fellow Marine Corps legend Carlos Hathcock held the highest kill count as a sniper with 93 — who still has one of the longest distance kills ever recorded at 2,500 yards.

It wouldn’t be until 1991 when one of Mawhinney’s spotters during Vietnam, Joseph T. Ward, wrote the book “Dear Mom: A Sniper’s Vietnam” and credited him with holding the record, citing that he had 101 kills.

At first, many weren’t aware of the book — Mawhinney included.

However, word slowly began to spread in the years to follow that Mawhinney was being credited with the most confirmed sniper kills in Marine Corps history.

It caused controversy amongst members of the sniper community, who still believed Hathcock held the record.

Peter Senich, a military historian and author specializing in sniping and small arms, went to verify Ward’s claim in the Marine Corps archives and found he was wrong. Mawhinney had 103 kills — not 101.

Mawhinney, a man who valued his privacy and was not seeking any fame for his actions in Vietnam, agreed to an interview with Senich in 1997, which was featured in the Baker City Herald.

“It’s an opportunity for me to get some recognition for a lot of the Vietnam vets that didn’t receive any recognition,” Mawhinney said.

“We were all there together. If I have to take recognition for it that’s OK, because every time I talk to someone, I can talk about the vets. It gives me an opportunity to talk about what a great job they did.”

Following his interview and newfound fame amongst the military community, Mawhinney retired from the US Forest Service in 1997 and began attending events across the country with his wife, Robin.

The legendary sniper told his life story to author Jim Lindsay, who wrote the book “The Sniper: The Untold Story of the Marine Corps’ Greatest Marksman of All Time” in March 2023.

“He was a good man,” said Lindsay in an interview with The Oregonian Wednesday, sharing that Mawhinney never bolstered about his kills and said he “did what I was trained to do.”

“He was a good father, a good husband and an asset to the community. He was a pretty cool cat.”

Mawhinney leaves behind a wife and three children.
