The M320 Grenade Launcher Is Finally In The Marines’ Hands

For years, the Marine Corps has relied on the tried and battle-tested but tired M203 grenade launcher gracing their rifle muzzles, but the times, they are a-changin’. Only eight years after the Army got theirs, the Corps has finally gotten its hands on the M320 grenade launcher.

The 2nd Combat Engineer Battalion became one of the first Marine units to receive the new grenade launcher when they took them out to the range at Camp Lejeune, North Carolina, on June 6.

The most significant difference between the M320 and the M203 is the former’s ability to be used as a standalone system; the M203 is permanently affixed to a rifle. The old M203’s leaf leaf sight can mess with your weapon’s optics, too. But the sights on the M320 are more flexible, which makes you a bit likelier to hit, or at least land near, your target. The M320 loads from the side, which allows for longer projectiles with increased velocity, compared to those fired from the M203, an under-the-barrel breechloader.

“The M320 definitely provides our Marines with a more efficient weapon system,” Cpl. Nelson Gay, a squad leader with 2nd CEB said in a Marine Corps statement. “The M320 has an increased rate of fire, and also allows the operator to acquire their targets much faster; used as either a standalone weapon or on a host weapon, it’s an accurate and efficient system.”

The M320, like most grenade launchers, provides significant firepower to ground troops, allowing them to engage enemy combatants, obscure or mark areas with smoke, and hit targets or bad guys that aren’t reachable with direct fire.

While this is good news for the service, it’s sure to make plenty of current and former Marines remember an old Corps truism: We get everyone else’s hand me downs.

With the Army already producing a fancy new combat helmet, and the Corps just announcing they’ll finally have enough Enhanced Combat Helmets for all Marines, it makes you wonder where these M320s came from.

In completely unrelated news, the Army is looking at a replacement for the M320.

A search is ongoing for a Camp Lejeune Marine who is wanted in Virginia on a murder charge.

The Franklin County Sheriff's Office in Rocky Mount, Virginia, said Monday they have issued an arrest warrant for Michael Alexander Brown, 22, for second-degree murder as well as use of a firearm in commission of a felony in connection with a Nov. 9 homicide.

NEW YORK (Reuters) - U.S. Army Lieutenant Colonel Alexander Vindman should not fear retaliation over his testimony to the U.S. Congress in its impeachment inquiry into President Donald Trump, Defense Secretary Mark Esper said on Monday.

Vindman, now detailed to the White House National Security Council, has been targeted by Trump following his Oct. 29 congressional testimony. Trump tweeted that Vindman was a "Never Trumper witness," raising questions about potential fallout on his military career.

"He shouldn't have any fear of retaliation," Esper told a small group of reporters during a flight to New York, adding that he had reinforced the "no retaliation" message in a conversation with the secretary of the Army.

A senior Pentagon official told impeachment investigators that President Donald Trump's freeze on nearly $400 million in military aid to Ukraine posed a strategic nightmare for the Defense Department and put the American-allied country in a deeply dangerous position, according to impeachment inquiry testimony released Monday.
