#TDIDCH: May 23, 1967 - A public controversy erupts over the M-16, the basic combat rifle in Vietnam, when Congress hears reports that Soldiers in Vietnam are killed in firefights as a result of their new M-16 rifles jamming.

By this time, the M-16 had replaced the heavier M-14 as the standard rifle in Vietnam. The new rifle fired the lighter, faster, more destructive 5.56mm cartridge at the same effective range.

The M-16 was already a source of controversy in Vietnam. Troops were writing home with stories of Soldiers killed due to the inferior rifle. 54 years ago today, some of those letters were read on the House floor.
[4 of 11]

The stories are tragic:

Rifles failing at critical moments.

Team leaders killed while running up and down a line, desperately trying to clear M-16's.

Soldiers carrying extra grenades & jungle knives on patrol because they have no confidence in their rifle.
[5 of 11]

Upon hearing all these stories, the House Armed Services Committee launched an investigation. Months later, the investigating subcommittee released a 600+-page report detailing a litany of problems with the M-16.
[6 of 11]

The report explained that the M-16 had been rushed into production and then shipped to Vietnam despite Army Materiel Command's knowledge that the rifle hadn't met design specifications and was a flawed weapon.
[7 of 11]

Our troops in Vietnam were never given a fair shot with the M-16.

Unchromed chambers rapidly corroded in Vietnam's humidity. Unsuitable ammo powder caused buffer and bolt malfunctions. Worse, the rifle didn't fully extract expended shells.
[8 of 11]

Finally, the report made clear that units in Vietnam were not given enough supplies to lubricate or clean their M-16s. [Soldiers were asking their parents to send lubricant and cleaning kits to keep their rifles functioning.]
[9 of 11]

The 600+ page report is a sharp indictment of Army Materiel Command, detailing egregious failures with the rifle and revealing an astonishing, unforgivable story of bureaucratic incompetence and malfeasance.
[10 of 11]

Afterwards, significant modifications were made to the rifle [e.g. addition of a manual bolt closure, revision to the mechanical buffer to slow down cyclic rate] that made the rifle more reliable.
[END]

While the rifle improved, for many Vietnam veterans, however, the rifle never recovered its reputation.

Today, we're continuing the story of Ralph Puckett, the legendary Ranger awarded the Nation's highest honor by President Biden in the White House yesterday.
[2 of 48]

Yesterday we told the story of his valorous action in the Korean War that earned him that ceremony.

But the 94-year-old has already lived many lives, more than we could tell in a single tweet thread.
[3 of 48]

Ralph's story only begins with the fight for Hill 205 in November, 1950. Ralph was grievously wounded three times in that fight, ending his Korean War. He was evacuated to this US Army hospital in Japan the next day.

Ralph Puckett was alone, freezing, and wounded. His men – 51 Rangers and 9 Korean augmentation soldiers - were exhausted, shocked, surrounded.

He did the only thing he could fathom in that moment: exposed himself to the enemy to save his men.

It was November 1950 - the Army was mopping up the shattered remains of the North Korean Army. Since the shocking success of the Inchon landing, American forces were pushing the enemy back to China. The Korean War would be over by Christmas.

American’s dismay, Chinese intervention in the war changed all of that. By November 20, the Chinese had infiltrated hundreds of thousands of Chinese “volunteers” into North Korea, and had clandestinely positioned four armies in front of the still advancing US forces

WESTMORELAND'S LEGACY

In telling the 70 year history of the XVIII Airborne Corps, we've arrived at the period between 1962 and 1973. During this time, this man, William Westmoreland, was a large figure - perhaps the dominant figure - in our Army.
[2 of 6]

Westy's reputation was darkened by the Vietnam War.

In this tweet thread, our friend, Dr. @Erikhistorian, historian for @USArmyCMH, reexamines the man and his controversies.

Regardless of what you think about Westmoreland, these four videos are worth your time.

Let's start with Westmoreland's early life, education, and WWII service.

THE XVIII AIRBORNE CORPS DURING THE VIETNAM WAR

As we continue our journey through the past 70 years of XVIII Airborne Corps history, we find ourselves in the period between 1962 and 1973, a time in which the US became increasingly embroiled in the Vietnam War.
[2 of 7]

As we've seen, during this time, the 101st Airborne Division deployed to the Vietnam War for virtually the entire US commitment there. The XVIII Airborne Corps HQ and all other Corps units, however, were kept out of Vietnam, just as they were kept out of the Korean War.
[3 of 7]

SecDef Robert McNamara believed a showdown with the Soviets or other Communist friendly forces might occur at any time. Therefore, the XVIII Airborne Corps was kept back in the US as a ready reserve to deploy elsewhere if needed.

19-year-old Sergeant James Spears: “Have you ever been inside a hamburger machine? We just got cut to pieces by extremely accurate machine-gun fire.”
