When 120 Australian soldiers arrived in Vietnam in 1966, American commanders did not know what to make of them. The United States had half a million troops in the country. Entire divisions were sweeping through the jungle with helicopters, artillery, and air support on call. And here came the Australians. A little over a 100 men without fanfare or a press corps following them around. Just quiet professionals who unpacked their kit and disappeared into the trees. Three years later, the Pentagon was trying to copy

their methods and failing. The Australian Special Air Service Regiment did not just fight in Vietnam. They haunted it. The Vietkong gave them a name that would follow them for decades. Marang, Phantoms of the Jungle, because at any given moment, everything would be fine along a jungle trail. And then suddenly, every fighter in the area would be dead. That is how the enemy knew the Australians had arrived. But Vietnam was just the beginning. Over the next five decades, the SASR would fight in Borneo, East Teour, Afghanistan, and

Iraq, building a reputation so formidable that Allied commanders, special forces operators, and intelligence officers who worked alongside them started saying things that rarely get repeated in official channels. If you enjoy deep dives into elite military units and the battles that built their reputations, consider subscribing. To understand how, we need to go back to a barracks in Perth, Western Australia. In 1957, the Australian Army had been watching the British SAS operate. During the Malayan Emergency, small teams

slipped into the jungle, dismantling insurgent networks with surgical precision. The Australians saw the future of warfare in those patrols and wanted in. On July 25th, 1957, the Army stood up the first Special Air Service Company at Swanborn, a quiet suburb on the Western Australian coast. Just 16 officers and 144 other ranks. They borrowed the British SAS motto, who dares wins. Then they set about earning the right to use it. Their heritage ran deeper than the British model, though. They drew from World War II units like Z

Special Unit and the Coast Watchers, small teams of Australians who operated deep behind Japanese lines in the Pacific, surviving months in jungles so dense that conventional forces could not reach them. That DNA, the ability to survive and fight in small groups with minimal support, would define everything the SASR did for the next 60 years. Vietnam was the proving ground. Three squadron arrived in April 1966 attached to the first Australian task force at New Dot. And the way they operated was

unlike anything the Americans had seen. While US forces moved in platoon and company-sized elements with heavy fire support, the Australians went out in teams of four to six men. They moved more slowly than any other unit in the theater, even other special operations forces. Every step deliberate, every sound controlled. But the moment they made contact, everything changed. The Australians unleashed fire so intense and concentrated that the Via Kong believed they were engaging a force many times larger. The slow, methodical

approach followed by sudden overwhelming violence became the signature of the Australian Special Air Service Regiment. Even experienced Viaong infiltrators, fighters who had evaded US forces for years, walked straight into Australian ambushes. Over 6 years, Australian and New Zealand Special Air Service patrols conducted nearly 1,200 combat missions. They confirmed 492 enemy killed with another 106 possibly killed. Their own losses were almost incomprehensibly low. One killed in action. One died of wounds. 28 wounded

across 580 men. Many historians consider it the highest kill ratio of the entire war. And here is the detail that really caught American attention. The Australian Special Air Service Regiment did not just fight alongside US forces. They taught them. Australian operators provided instructors to the MACV recondo school, the premier reconnaissance training program in Vietnam. The students of American special operations were learning from Australian masters. The next time the SASR made international headlines was East Teour

in 1999. After a referendum showed overwhelming support for independence from Indonesia, militia groups launched a campaign of terror. Australia led the international response and three squadron SASR was first on the ground securing Dilly’s airport so the main peacekeeping force could arrive. On October 16th, a six-man covert reconnaissance patrol near Idabbasala, just 15 km from the West Teour border was detected while setting up an observation post. Within moments, more than 60 armed militia organized into

search teams and moved to surround them. The rear scout engaged fighters at a distance of just 20 m and the patrol fought a running battle for 90 minutes. They were attacked four separate times before a Blackhawk helicopter extracted them. Every Australian survived. The patrol commander was later awarded the Medal for gallantry by Queen Elizabeth. His reaction was typical of the Special Air Service Regiment. He said he didn’t think what he did was as brave as some. Then came September 11th and everything

accelerated. Australia was among the first nations into Afghanistan. By December 2001, one squadron of the Special Air Service Regiment was conducting long range vehicle patrols covering hundreds of kilometers around Kandahar and deep into the Helman Valley, hunting al-Qaeda and Taliban positions that larger forces could not reach. They drove heavily modified longrange patrol vehicles through some of the most hostile terrain on Earth, operating at altitudes above 7,500 ft in freezing conditions with limited

resupply. On February 16th, 2002, Sergeant Andrew Russell became the first Australian killed in Afghanistan when his vehicle struck a landmine in the Helman Valley. Two other soldiers were wounded. The regiment absorbed the loss and kept moving. The moment that put them on the map with American leadership was Operation Anaconda in March 2002. The Shaika Valley had become a gathering point for al-Qaeda fighters and coalition forces planned a massive operation to destroy them. But intelligence was wrong. The enemy was

far larger and far more entrenched than expected. Dug into prepared positions and caves that dated back to the Soviet war. When United States infantry from the 10th Mountain Division landed in the valley, they walked into a storm of mortar and machine gun fire from the surrounding mountains. On a neighboring ridge, an observation post from the Special Air Service Regiment watched the disaster unfold. Fog had grounded surveillance drones. American soldiers were pinned down, taking casualties in danger of being overrun. The Australians

became the coalition’s eyes. They had used virtual reality style mission rehearsal software before insertion. The first time that capability had been used in live combat and their situational awareness in the darkness and poor weather was exceptional. They coordinated air strike after air strike onto enemy positions, directing bombers with precision that prevented al-Qaeda fighters from closing on the wounded American soldiers. An Australian signalman named Martin Wallace exposed himself to enemy fire to drag wounded

American soldiers from 187 infantry into a creek bed and treat their injuries, earning the medal for gallantry. Lieutenant General Frank Hagenbeck, the coalition commander, later said he would not have wanted to conduct that operation without the Australian Special Air Service on that ridge line. He said they made it happen that day. The special air service regiment commander received the United States Bronze Star for his unit’s contribution. In September 2008, the battle of Ka Orusen tested the regiment again. Two SASR

patrols in a US special forces element from the seven special forces group were ambushed in a valley in Uros gun province during a joint operation. The coalition force had set up sniper positions in the foothills and was moving through the valley in a convoy of five Humvees when accurate mortar fire and small arms opened up from the ridgeel lines. The fire was so intense one patrol commander described it as rain on the surface of water. SASR snipers dismounted from the vehicles and moved into the foothills to provide

covering fire while the convoy crawled through rocky terrain at walking pace. Nine SASR operators were wounded. In one fiveman patrol, only a single member escaped injury. A US special forces dog handler was killed. They fought for over 9 hours, expending nearly all their ammunition before fighting their way out. The Taliban sustained an estimated 80 killed. An Australian explosives detection dog named Sarby disappeared during the battle when a rocket explosion snapped her leash. She spent nearly 14 months missing in action

before an American soldier spotted her with a local Afghan man. Her recovery generated worldwide news and was mentioned by both the Australian Prime Minister and General Stanley Mcrist. Before the Afghanistan dust had settled, the Australian Special Air Service Regiment SASR was already proving itself in Iraq. In early 2003, one squadron deployed for Operation Falconer. Their mission was securing western Iraq to prevent escud missile launches toward Israel. The exact scenario that had nearly fractured the Gulf War coalition

12 years earlier. They entered by vehicle and helicopter, working alongside the British 22nd Special Air Service Regiment to seize the strategically critical H2 and H3 airfields in armed Land Rover convoys, neutralizing guard towers and defensive positions before clearing the facilities. They fought running vehicle battles across the open desert with Iraqi soldiers who engaged them with machine guns mounted on pickup trucks. They located and destroyed seud launch sites. They patrolled the highways to

block the escape of Iraqi government officials and prevent foreign fighters from entering the country. And on April 11th, they captured the Al-Assad air base, one of Iraq’s largest military installations. Inside they found more than 50 MIG fighter jets hidden in camouflage shelters and over 7.9 million kgs of explosives. The Australians secured it all, repaired the runways and turned the captured base into a functioning forward operating point for coalition aircraft. So what made the SASR different from every other special

forces unit their allies had worked with? Part of it was the selection process. Only about 10 to 15% of candidates who begin the course complete it. During the first phase, candidates burn nearly 7,700 calories a day while consuming roughly half that. The course involves force marches, navigation in remote terrain, sleep deprivation, and cognitive tasks designed to break down nearly everyone. It is not looking for the strongest. It is looking for the ones who can still think and still function as a team when

everything in their body says quit. Part of it was the small unit doctrine baked in from day one. Every SASR patrol member carries capabilities that would be spread across an entire platoon in a conventional unit. Navigation, survival, communications, demolitions, sniping, advanced medical skills, self-sufficiency taken to its absolute extreme, and part of it was the culture. While other special forces units produced memoirs and Hollywood consultants, the Australians maintained a wall of silence

that frustrated journalists and fascinated intelligence professionals in equal measure. The operators let their missions speak, then deflected attention with the kind of dry understatement Australians are famous for. Two decades of continuous combat took a toll on this small force. A few hundred operators carried a disproportionate share of Australia’s combat burden, and that sustained pressure pushed some individuals past the breaking point. The regiment confronted those failures through internal reform and oversight

changes that continue today. But the operational reputation built over 60 years remains intact among the allies who served alongside them. American, British, and coalition operators who shared battlefields with the SASR consistently described the same thing. Quiet professionals who arrived without fanfare, operated with terrifying precision, and disappeared before anyone could ask too many questions about what happened on the objective. The North Vietnamese called them phantoms. The coalition in Iraq watched them secure an

area the size of some European countries with a single squadron. and the operators who worked alongside them in Afghanistan’s most dangerous valleys learned a simple unspoken rule. You do not ask the Australians what happened out there. You just trust that the job got done.
