History of the 173d Airborne Brigade
Craig Thompson email --- firstname.lastname@example.org
March 26, 1963 — On the island of Okinawa, the only separate Airborne Brigade to exist in the history of the US Army was activated. This was the 173d Airborne Brigade (Separate).
Formed to be what would be called in today’s jargon a quick-reaction force for the protection of American interests in Asia, the Brigade underwent extensive jungle training on Okinawa and Irimote. This was followed by parachute jumps in the Philippines; Thailand and Taiwan.
During the Taiwan exercises, the locals gave the paratroops of the 173d the nickname “Tien Bing” (Chinese for Sky Soldier). “The Sky Soldiers” became the official nickname of the Brigade and was commonly used in Brigade newsletters and press releases. A more popular nickname is one that originated from some anonymous pundit in the ranks – “The Herd.”
On May 5, 1965, the Brigade deployed to South Viet Nam as the first US Army ground combat unit in that war.
Upon arrival, one battalion of the Royal Australian Army and a battery from New Zealand were attached to the Brigade — making the 173d Airborne the only multi-national combat unit in the war.
Initially headquartered in Bien Hoa, the Brigade operated in the four provinces around Saigon. (Xuan Loc, Long Khanh, Phuoc Long & Phuoc Tuy), but (in its roll as a “Fire Brigade”) also went to the Central Highlands (Pleiku / Kontum) to fight Viet Cong. The 173d also conducted constant operations against the southern stronghold of the VC Main Force in the legendary Iron Triangle in War Zone D.
At 0900 Hours, February 22, 1967 (during Operation Junction City) over 800 paratroopers jumped into the rice paddies at Katum in War Zone C. The same unit (plus attached combat engineers and artillerymen) that had made the famous jump on the Island of Corrugators (2/503d) during WW2, made the first and only full-sized combat jump by an American unit (there were Vietnamese jumps of course and some small unit jumps by USMC’s Force Recon as well).
Once on the ground, the paratroopers joined the Brigade in cutting off VC units fleeing a massive sweep by the 1st, 4th, and 25th Infantry Divisions, and the 11th Armored Cavalry regiment.
In the summer of 1967, the Brigade saw extensive and bloody action in the Central Highlands near Kontum, Pleiku, Dak To.
In mid-November of 1967, the 2d Battalion of the 503d Airborne Infantry pushed units of the 1st and 10th North Vietnamese Army Divisions towards the Cambodian/Laotian borders. To cover their retreat into these sanctuaries the elite NVA 174th Infantry Regiment was deeply entrenched in a complex of fortified bunkers on Hill 875, near Dak To. On November 6th, two companies from 4th battalion encountered elements of the NVA 66th Regiment south of Ben Het and in a fierce firefight lost 7 men. On November 11th (Veteran’s Day), Charlie Company and two platoons from Delta Company 1/503 were ambushed with 20 killed and 154 wounded. PFC John Barnes received the CMH for his actions during this ambush.
On November 19th, 1967, the 2d Battalion of the 503d Airborne Infantry was ordered to clear Hill 875. Resistance by the communists was intense and the 4th Battalion of the 503d joined 2nd battalion in its efforts.
Four days later, on Thanksgiving Day, after some of the bloodiest fighting of the war, the survivors of the 2d and 4th Battalions finally reached the summit. Chaplain Watters and PFC Carlos Lozada received the CMH for their heroism on Hill 875. The 2nd battalion lost 107 men killed and 282 wounded and 10 MIA.
In 1968 the majority of the Brigade was stationed in the province of Binh Dinh. Operations were also conducted in the Central Highlands and near Ban Me Thout.
For the next four years the Brigade conducted operations against VC/NVA forces. Not as frequently noted as it should be, the Herd also provided security for medical teams involved in MEDCAP; training of indigenous forces for self-defense; and other programs designed to undermine the VC infrastructure in the rich rice-growing lands of the Coastal Plain. Emphasis was on small unit patrols and combined operations with ARVN/MSF/RF-PF units.
The 173d Airborne Brigade took part in 14 designated campaigns in RVN. It remained in combat longer than any other American military unit since the Revolutionary War. It earned four unit citations, had 12 Medal of Honor winners, 1601 Sky Soldiers were killed in action and another 8,435 were wounded in action.
The 10,041 casualties incurred by the Brigade were five times greater than those suffered by the 187th Airborne Regiment in Korea, four times greater than those suffered by the 11th Airborne Division in the Pacific during World War II, more than twice those suffered by the 101st Airborne Division in Europe in World War II, and two-thirds of those suffered by the entire 82nd Airborne Division in WW2.
In September 1971 the Brigade was redeployed to Fort Campbell, Kentucky and subsequently on January, 14, 1972 was deactivated.
I believe that the 503d Infantry Regiment has been reactivated as a non-Airborne unit and is part of the 2nd Division in Korea.
1. Opord 5- 17-65 7 May – 9 July 1965 Bien Hoa Area

8. NEW LIFE 21 November – 17 December 1965 La Nga River Valley
The 173rd moved three infantry battalions, four artillery batteries, the Calvary troop and the command section by air to Vo Dat. The brigade’s mission was to prevent the rice harvest in the area from falling into the hands of the VC. For the first time, the brigade used the Long Range Patrols (LRPs), these small patrols would usually be infiltrated by helicopter deep into the enemy rear where they would operate independently for weeks at a time.

The 173D Airborne Brigade (SEP), including elements of the 1st Royal Australian Regiment, conducted a hellebore assault near the Song Be River in War Zone “D” to initiate Operation Silver City. The first few days of the operations consisted of thorough screening of the area, leading to the discovery of vast quantities of food, munitions, bunkers, tunnel systems documents, and several large VC base camps.
The seventh day of Operation Silver City will long be remembered by the troopers of the 173D, for on this day the 2/503rd Infantry Task Force was attacked from all directions by the 501st VC Battalion. The troopers held their perimeter while inflicting heavy losses on the guerrillas. Resupply of needy ammunition was effected during the battle by helicopter at no small risk to equipment and crews. Numerous tactical air strikes were initiated with great effectiveness. The VC had to resort to chaining their machine gunners to the tripods of their weapons, but even these measures could not stop the crack troopers of the 173D.
The 1st Battalion, 503d Infantry was directed to reinforce the 2nd Battalion during the battle. The VC element was nearly annihilated by this time and chose to break contact rather than tackle two battalions of SKY SOLDIERS. Four hours after initial contact, all VC were routed or destroyed.

The Battle of the Slopes began as a routine search and destroy mission involving the 2/503rd. A company began leaving its night auger when its point squad ran into several NVA’s. An intense firefight occurred preventing 2nd platoon from linking up with its point squad. A company perimeter came under attack by the NVA cutting off the 2nd and 3rd platoons. The 1st and 2nd platoons were down to fifteen effective men when radio contact was lost. The 2nd platoon withdrew his remaining men to the Company Command Post, which then moved back up the ridge to a more defensible position. Two more enemy assaults were made on A company’s CP before C company would hook up with them.
The NVA’s 24th Regiment was well dug in and prevented C company from linking up with the lost platoon. That night, while anticipating an all out attack, the men heard shots punctuated by screams as the NVA executed the wounded. 43 out of 76 slain Sky Soldiers had fatal wounds in the back of their heads.

Seven Sky Soldiers fell from enemy bullets. On Veteran’s Day Task Force Black made up of elements of C/1/503 and two platoons of from D/1/503 were ambushed. American losses from the ambush were 20 killed, 154 wounded and 2 missing. PFC Barnes was awarded the Congressional Medal of Honor because of this action.
On November 19, the 2/503d Infantry began climbing Hill 875. Companies C and D were hit with automatic weapons fire as they reached the first of two ridges. As the men moved up and spread out on line they came under fire by recoilless rifle fire and rifle grenades. A Company secured the rear when it came under intense attack by the NVA. PFC Carlos Lozada received the Congressional Medal of Honor for holding off the enemy while the remainder of the company made its way up the hill to join the rest of the battalion.
The enemy had prepared the battlefield extremely well. Hill 875 was no less than a fortress, with bunkers and trenches connected by tunnels. The underground bunkers had as much as two meters of overhead cover to protect their occupants from bombing and artillery, and slit gun ports opened onto excellent fields of fire. When the NVA infantry went on the attack, the soldiers were camouflaged and had prepared avenues of entry and withdrawal from the battlefield.
Chaplain Charles Watters was moving among the wounded men administering last rites when a jet fighter diving at over 300 miles per hour dropped a 500-pound bomb on the embattled battalion killing 42 troopers. He was also awarded the Congressional Medal of Honor for this engagement.
On Thanksgiving Day the 4th Battalion assaulted up the hill with the remainder of the 2nd Battalion, taking the peak at 1122. The capture of the Hill 875 marked the climax of the battle of Dak To. The 2nd battalion lost 107 men killed and 282 wounded and 10 MIA.
