You’ve seen them in the background of every major televised event at the White House or the Pentagon. Those soldiers with the razor-sharp creases, the silver-capped boots, and the eerie, clockwork precision. They’re the 3rd U.S. Infantry Regiment, but everyone just calls them The Old Guard. Honestly, most people think they’re just there for the aesthetics. They assume it's a ceremonial unit full of guys who just polish brass all day.
That's a mistake.

The Old Guard is actually the oldest active-duty infantry regiment in the U.S. Army, dating all the way back to 1784. While they do spend an absurd amount of time obsessing over the distance between a medal and a pocket flap, they are first and foremost combat-ready soldiers. If things ever got truly ugly in Washington D.C., these are the people responsible for defending the capital. They aren't just "stage dressing." They are elite infantry.
The Brutal Reality of Guarding the Tomb of the Unknown Soldier
Most people know The Old Guard because of the Tomb of the Unknown Soldier. It’s the most famous post in the military, and it’s basically a masterclass in suffering for your craft. You might think it’s just walking back and forth, but the physical toll is wild. They do it in 100-degree humidity. They do it in blizzards. They do it when the wind is literally trying to knock them over.
There’s this persistent myth that the Sentinels aren’t allowed to drink alcohol or watch TV for the rest of their lives after serving at the Tomb. That’s total nonsense. It’s one of those "internet facts" that just won't die. In reality, the restrictions are intense during their tour of duty, but once they hang up the uniform, they're just regular veterans.
What it takes to earn the Badge
The Tomb Guard Identification Badge is the second-least awarded badge in the entire Army. Only the Astronaut Badge is rarer. Think about that for a second. To get it, you have to pass a series of tests that would make most people quit in a heartbeat. You have to memorize 35 pages of Arlington National Cemetery history—verbatim. If you miss a comma or a period during the oral exam, you fail.
The walking itself? It's 21 steps. Then a 21-second pause. Then another 21 steps. Why 21? It symbolizes the 21-gun salute, the highest honor given to any dignitary. If you watch them closely, you'll see they carry their rifle on the shoulder away from the Tomb. It's a sign that they are standing between the public and the honored dead. It’s a literal shield.
More Than Just Arlington
While the Tomb is the face of the unit, The Old Guard handles a staggering variety of missions. They have the Caisson Platoon, which uses those massive, beautiful horses to carry fallen heroes to their final resting place. If you've ever been to Arlington and heard the clip-clop of hooves on the pavement, you know how haunting that sound is.
Then there’s the Presidential Salute Battery. They’re the ones firing the cannons for visiting heads of state. It's not just "point and shoot." It requires timing so precise it feels digital. They also have the Continental Color Guard, who wear the old-school 1784-style uniforms with the powdered wigs and tricorn hats. It looks a bit goofy if you aren't used to it, but it’s a direct link to the Revolutionary War.
The specialized units you didn't know existed
- The U.S. Army Drill Team: These guys throw 1903 Springfield rifles with fixed bayonets around like they’re made of plastic. It’s terrifying to watch up close.
- The Fife and Drum Corps: They play music from the 1700s. It sounds niche, but they are the only unit in the military that doesn't have to salute. Why? Because in the 18th century, musicians' hands were always full of instruments.
- The Commander-in-Chief’s Guard: They are the ones you see in the fancy dress uniforms during the State of the Union or at the inauguration.
The "Toy Soldier" Misconception
I've talked to guys who served in the 3rd Infantry, and they get pretty annoyed when people call them "toy soldiers."

Every single person in The Old Guard is a fully qualified infantryman. They go to the same basic training as the guys in the 82nd Airborne or the 10th Mountain Division. They still go to the range. They still do rucksack marches. They still practice urban warfare tactics. In fact, many of them come to the unit after serving in combat zones like Iraq or Afghanistan.
Being in The Old Guard is actually harder in some ways than being in a regular line unit. In a standard infantry squad, nobody cares if your boots are a little scuffed or if you haven't shaved in two days when you're out in the field. In the 3rd Infantry, a single stray thread on your sleeve is a "major deficiency." You have to maintain elite combat readiness while also maintaining a level of perfection that is physically exhausting. Imagine doing a 12-hour shift on your feet, then going home and spending four hours with a lighter and a tin of Kiwi polish just so your shoes look like glass the next morning. It’s a grind.
The Logistics of Perfection
Let's get into the weeds of how they actually look that way. It's not magic. It’s chemistry and physics.
They use "edge dressing" on the sides of their soles to make them stay pitch black. They use "scuff cover" on the heels. The medals on their chest aren't just pinned on; they are precisely measured with a ruler. If a medal is 1/64th of an inch off, they have to start over. Most soldiers in the 3rd Infantry have a "uniform room" in their house where they keep their gear. You don't just throw this stuff in a closet.
The boots are the craziest part. They don't just buy them off the shelf. They use "clickers"—metal plates on the heels—to create that distinctive sharp sound when they march on the stone at Arlington. It adds a layer of auditory intimidation and rhythm to the ceremony.
Why We Still Need The Old Guard in 2026
You might ask why we spend tax dollars on a unit that spends so much time on ceremony. In an era of drones, cyber warfare, and AI, does a guy in a 1780s wig really matter?
Honestly, yeah.
The Old Guard is the physical manifestation of the Army’s "lineage." They are the keepers of the culture. When a family is burying a loved one at Arlington, they don't want a drone or a pre-recorded message. They want the highest level of human respect possible. They want to see a soldier who has spent hundreds of hours perfecting a salute just for their father or mother. It’s about the "last full measure of devotion."

Beyond the sentimentality, there's a practical side. The 3rd Infantry is part of the Military District of Washington (MDW). Their job is "Defense Support of Civil Authorities." This means if there’s a natural disaster, a massive protest that turns into a riot, or a terrorist attack in D.C., The Old Guard is the immediate response force. They know every tunnel, every hallway, and every security protocol in the capital.
A Quick Reality Check on the Requirements
If you’re thinking about joining, know that they have strict height requirements. Traditionally, men have to be between 5'10" and 6'4", and women have to be between 5'8" and 6'2". They want a uniform look across the line. If you’re 5'2", you’re probably not going to be a Sentinel, no matter how good your "21 steps" are. It’s one of the few places in the modern world where "looking the part" is a literal job requirement.
What Most People Get Wrong About the Uniforms
You'll see people online arguing about the "blue" versus "green" uniforms. Historically, the Army wore "Army Green," but The Old Guard was one of the few units that always kept the "Blues" for ceremonial duties. Now, the rest of the Army has moved toward the "Army Green Service Uniform" (the pinks and greens), but The Old Guard still rocks the blues for high-level events.
Also, those sunglasses? The Sentinels at the Tomb wear them not because they want to look like The Matrix, but because the reflection off the white marble is blinding. It’s a health necessity. Without them, they’d have permanent eye damage within a few months of duty.
How to Respectfully Watch The Old Guard
If you go to see them, please, for the love of everything, stay behind the rails. Every year, there’s some tourist who tries to cross the line at the Tomb of the Unknown Soldier to get a better photo. The Sentinels are allowed to break their silence to yell at you. It is loud, it is scary, and it will be the most embarrassing moment of your life.
They will bring their rifle to "Port Arms" and shout: "It is requested that all visitors maintain a high level of silence and respect!" That’s the polite way of saying "Get back before I treat you like a threat."
Actionable Steps for Enthusiasts and Aspiring Soldiers
If you’re fascinated by the 3rd Infantry Regiment or considering a path toward the unit, here is how you actually engage with them:
- Visit the Twilight Tattoo: During the summer months, The Old Guard puts on a free sunset performance at Joint Base Myer-Henderson Hall. It’s the best way to see the Drill Team, the Fife and Drum Corps, and the horses all in one spot without the somber atmosphere of a funeral.
- Check the "H-Series" MOS: If you’re joining the Army and want in, you need to talk to a recruiter specifically about 11B (Infantry) with an assignment to Fort Myer. Be warned: you’ll still have to pass the internal "proffering" process once you get there.
- Study the Blue Book: If you're a gear nerd, look up the "3rd Infantry Regiment (The Old Guard) Blue Book." It's the literal manual for their standards. Reading it will make you realize how sloppy your own suit or uniform probably looks.
- Support the Caisson Barn: You can actually visit the stables where the horses are kept. They are always looking for volunteers and support, and it’s one of the few parts of the unit that feels "human" and less like a machine.
The Old Guard isn't just a relic of the past. It's a weird, intense, and highly specialized community that bridges the gap between 1784 and 2026. Whether they are guarding a tomb in a hurricane or standing behind a President, they represent the idea that some things—like discipline and memory—are worth the effort of being perfect.
