Marine Snipers in Vietnam

They often worked in pairs.

They carried rifles capable of reaching farther than the standard infantryman's weapon, moved quietly through terrain controlled by the enemy and sometimes spent hours—or days—waiting for a single opportunity.

During the Vietnam War, Marine snipers became some of the most effective individual marksmen on the battlefield.

But their importance went far beyond the number of enemy soldiers they killed.

Vietnam helped transform Marine Corps sniping from a capability that had repeatedly appeared and disappeared throughout the Corps' history into a specialized discipline built around fieldcraft, observation, precision shooting and intelligence.

Names such as Carlos Hathcock became famous.

But Hathcock was only one Marine among a much larger group of scout snipers who quietly hunted the enemy throughout South Vietnam.

Their story helped shape the Marine scout sniper tradition for generations.

Snipers Before Vietnam

Sniping was hardly new to the Marine Corps.

Marine marksmen had demonstrated their abilities in earlier conflicts, and precision rifle fire had been used during both World Wars and Korea.

The problem was continuity.

After wars ended, specialized sniper programs often diminished along with them. Training, equipment and battlefield knowledge could disappear as experienced Marines left the service.

Vietnam forced the Corps to rebuild that capability.

American forces faced an enemy that understood concealment exceptionally well.

Viet Cong guerrillas and North Vietnamese Army soldiers used jungle, elephant grass, villages, tunnels and carefully prepared fighting positions to hide their movements.

Finding them could be as difficult as killing them.

A trained sniper offered something ordinary infantry units could not always provide:

A Marine whose primary job was to observe without being seen—and strike precisely when the opportunity appeared.

Building the Marine Sniper Program

As Marine involvement in Vietnam expanded during the 1960s, efforts were made to establish formal sniper training in theater.

Marine units developed sniper schools where selected Marines learned skills far beyond simply firing a rifle accurately.

Marksmanship was only the beginning.

A sniper needed to understand camouflage.

Movement.

Observation.

Range estimation.

Target detection.

Stalking.

Fieldcraft.

And perhaps most importantly, patience.

A Marine who could consistently hit a target on a rifle range was not automatically a sniper.

The sniper had to reach a firing position without being detected, identify the correct target, make the shot and survive long enough to return.

Vietnam provided a brutal classroom.

The Sniper Team

Marine snipers generally did not operate as lone gunmen wandering through the jungle.

They commonly worked as teams.

One Marine might concentrate on the rifle while another helped observe the surrounding terrain, identify targets and watch for threats.

The observer could help estimate distance and conditions affecting the shot.

Just as importantly, another set of eyes helped protect the sniper.

A sniper staring through an optic had a limited field of view.

Someone needed to watch everything else.

The team might move ahead of friendly positions, establish an observation point and wait.

Sometimes nothing happened.

Hours could pass.

Then a figure might appear hundreds of yards away.

The entire mission could suddenly come down to a few seconds.

Hunting the Enemy

Vietnam presented unusual opportunities—and enormous dangers—for sniper teams.

The enemy often moved along trails, waterways and approaches that could be observed from concealed positions.

Snipers learned to study patterns.

Where did enemy soldiers cross a trail?

Where were supplies being carried?

Where had someone repeatedly appeared?

Where was enemy fire coming from?

A successful sniper did not simply look for a target.

He studied the battlefield.

That information could itself be valuable.

A sniper team observing enemy movement could report what it saw even when no shot was fired.

In that sense, the sniper was also a reconnaissance asset.

That relationship between scouting and precision shooting became fundamental to the Marine scout sniper concept.

The Rifles

Marine snipers in Vietnam used several rifles as the sniper program evolved.

One of the best known was the Winchester Model 70, a bolt-action sporting rifle renowned for its accuracy.

Some Model 70s were fitted with telescopic sights and used effectively early in the war.

But commercial sporting rifles were not an ideal long-term solution for a military sniper program.

The Marines eventually adopted the M40 sniper rifle, based on the Remington Model 700 bolt-action rifle.

Chambered in 7.62×51mm NATO, the original M40 was fitted with a Redfield telescopic sight.

It gave Marine snipers a standardized precision rifle specifically selected for their mission.

The M40 would prove enormously influential.

Improved versions remained associated with Marine scout snipers for decades.

One Shot

The sniper's greatest advantage was precision.

An infantry unit encountering an enemy position might require machine guns, grenades, mortars, artillery or air support to suppress it.

A sniper sometimes needed one cartridge.

The effect could be greater than simply removing one enemy soldier.

A hidden marksman created uncertainty.

Enemy troops might know approximately where a shot originated but not exactly where the Marine was concealed.

Movement became dangerous.

Leaders exposing themselves became targets.

Soldiers sent to locate the sniper could themselves be observed.

A skilled sniper could influence a much larger area than the small piece of ground he physically occupied.

Chuck Mawhinney

Among the most successful Marine snipers of the Vietnam War was Charles "Chuck" Mawhinney.

Mawhinney served with the 5th Marine Regiment in Vietnam and spent much of his combat tour operating as a scout sniper.

Unlike some famous warriors, Mawhinney did not spend the years following Vietnam promoting his wartime record.

He returned home and largely kept his experiences to himself.

For years, even many people who knew him had little idea what he had done.

Marine Corps records eventually credited Mawhinney with 103 confirmed kills and 216 probable kills during his Vietnam service.

That made him one of the most successful snipers in Marine Corps history.

Yet the numbers alone do not explain his effectiveness.

Mawhinney's experiences illustrated the qualities Marine sniper training sought to develop: patience, fieldcraft, judgment and the ability to make accurate shots under combat conditions.

More Than a Kill Count

Snipers are often discussed almost entirely in terms of confirmed kills.

That can obscure much of what they actually did.

A sniper mission might involve spending an entire day watching a suspected enemy position without firing.

That could still be a successful mission.

Information about enemy movements, weapons, defensive positions and routes could be passed back to commanders.

A sniper might also provide overwatch for Marines operating in exposed terrain.

Enemy troops attempting to fire on a patrol could suddenly find themselves exposed to precision rifle fire.

The sniper was simultaneously a marksman, observer and scout.

Camouflage and Fieldcraft

The jungle could conceal a Marine.

It could also betray him.

A broken branch, disturbed vegetation or unnatural movement might reveal a sniper's position.

Marine snipers learned to use vegetation and camouflage to break up the recognizable outline of the human body.

Movement had to be deliberate.

Sometimes extraordinarily slow.

A sniper attempting to approach an enemy position might move only a short distance over a long period of time.

Speed was rarely the goal.

Remaining unseen was.

The best firing position was useless if the enemy saw the sniper enter it.

Waiting

One of the hardest sniper skills could not be measured on a rifle range.

Waiting.

Heat.

Mosquitoes.

Rain.

Mud.

Thirst.

Fatigue.

And the knowle
