Why Everyone HATED British Boys AT Rifle

Added: 2026-05-07

[00:00:03]This anti-tank rifle is arguably one of the most unique weapons of World War II.

[00:00:08]Its name is Boy's anti-tank rifle made by the British designer Henry Seabo exactly to knock out the tanks of the 1930s. But what the British designers didn't know was that tank technology was about to advance beyond belief during the German invasion of France. And soon the boys would start malfunctioning in unbelievable ways. And ironically, the first time the boy's rifle would see use wasn't in British hands at all, but in Finnish ones, where the gun actually performed excellently. You see, in late 1939, the Soviet Union invaded Finland with thousands of tanks in what would be called the Winter War, and the Finns only had the old Renault FT tank from World War I and a few others. So, Britain shipped them around 200 boys rifles as emergency aid, and the Fins gave it the name 14 mm PST K37. And the timing was almost too good because the main Soviet tanks rolling across the border were the T-26 light tank and the BT5, both with thin armor that the boys could punch straight through at close range. A Finnish gunner would lie in the trees or foliage with the rifle on its bipod, wait for a tank to come close and put a 14 mm round straight through the side armor into whoever was inside. The T-26 also had a nasty habit of catching fire pretty easily once the armor was breached, which made things even better for the Fins. But Soviet tank crews quickly realized they had to start fighting buttoned up at all times, and even that wasn't always enough to save them. The boys had finally proven what it was actually built for. But back in London, the British were about to find out that the Fins had been rather lucky and only just utilized the gun in its most perfect window of opportunity.

[00:01:40]Because Finland's Winter War was being fought against tanks designed in the early 1930s, while the Germans were already building something completely revolutionary. So when the boys finally got into British hands in real combat, the story was going to look absolutely nothing like in the Winter War. Now the original idea behind the boys was actually quite reasonable on paper. In 1934, the British army wanted a rifle that one infantryman could carry that fired a bullet big enough to punch through 16 mm of armor at 100 yards and that could be mass- prodduced cheaply.

[00:02:11]Captain Henry C. boys at the Royal Small Arms Factory in Enfield led the team and they took inspiration from a Polish anti-tank rifle called the WZ35. So they scaled up the American 50BMG cartridge, necked it up to 0.55 in, added a belt to the case for strength, and called the new round the 0.55 boys. The rifle itself was bolt action, fed from a five shot magazine on top, weighed about 36 lb, and was over 5 ft long. And the original code name for the project was Stansion. But Henry himself died only days before his rifle was officially adopted in November 1937. So it was renamed the boys in his honor. So the rifle worked perfectly fine in testing, going through about 23 mm of armor at 100 yards, which was exactly what was needed against the tanks of the early 1930s. But by the time the Germans invaded Norway in April 1940, those early 1930s tanks were already history.

[00:03:05]British troops were sent to help defend Norway. And on the 22nd of April 1940 near Balberg Hill in the Goodbrd doll valley, they actually got one of the first kills ever scored on a German tank by British ground forces. It was one of the rare German Nobel heavy tanks and the boys hit it dozens of times until a crew member was killed and the tank pulled back. The first fifth Leers then made a stand the next day at the village of Trenton where more boys rifles were used against German armor. And for a brief moment, it actually looked like the rifle was earning its keep. However, what nobody back in London realized yet was that those Norwegian kills were the last good news the boys would ever get from a European battlefield because the next time it went into action, it would be in France against the full weight of a Panza division. As the Germans launched their invasion of France, they brought thousands of tanks with them in May 1940. Now, most of the German armor at this point was still relatively light. The Panza 1's and Panza 2s along with early Panza 3es made up the bulk of the German force. On paper, the boys should have been able to handle these, especially the Panza one, which only had about 13 mm of armor. But once the actual fighting started, the rifle's reputation completely fell apart. You see, hitting a moving target at long range with a bolt-action rifle that kicks like a mule is much harder than hitting a stationary target on a calm range in England. The recoil was so brutal that gunners would come back from a single shot with bruised shoulders, neck strains, and sometimes a proper bloody nose if they held the rifle wrong. Australian troops nicknamed the gun Charlie the Bastard because of the kick. While the Canadians called it the Jinx, and one veteran said you needed an awful good reason to actually pull the trigger. So even when the round did connect, the German tanks had often improved their armor just enough that the bullet would either bounce off or fail to do meaningful damage to the crew inside. At the Battle of Bologn on the 23rd of May 1940, Welsh Guardsman Doug Davies later remembered watching a German tank commander actually laughing at the British fire from his position outside the town. The Welsh guards were getting hammered with their boys rifles bouncing off enemy armor while the panzas just kept rolling forward. And this was the moment when the British infantry started to figure out something terrifying about their main anti-tank weapon. It wasn't just hard to use, it was sometimes useless against the very tanks it was supposed to kill. There were a few exceptions worth mentioning, like Sergeant William Gilchrist of the Irish Guards at Bologn the same week, who actually managed to set a German tank on fire with his boys and blocked the street long enough for his battalion to withdraw. But these stories were the exception, not the rule. After the British were forced into the disaster of Dunkirk, they left behind massive amounts of equipment on the beaches, including thousands of boys rifles. The Germans collected them, designated them the Panzer Robu Busussa 782, and even sold the batch back to Finland later in the war. So, the British were now fighting with a rifle that had failed in France, while the Germans were learning from it and improving their tanks even further. And it was about to get even worse because the British high command came up with what was probably the dumbest idea anyone could have for this weapon. They decided to make it even shorter and give it to paratroopers.

[00:06:12]After Dunkirk, the boy's reputation was so bad that the Canadian government actually paid Walt Disney Studios to make a training film called Stop That Tank in 1942. The whole point of the cartoon was to convince Canadian soldiers that the boys wasn't actually cursed because troops were genuinely starting to refuse to use it. Disney made a cartoon where Hitler himself was being terrified by the rifle. But no amount of animation was going to change what the gun actually did on the battlefield. By 1942, someone in the British Army decided that paratroopers needed their own version of the boys.

[00:06:44]So, they took the standard rifle, chopped about a foot off the barrel, removed the muzzle break to save weight, and called it the Mark 2. This was meant to be dropped from aircraft alongside airborne troops who would use it to defend themselves against German tanks until heavier weapons arrived. But there was one major catch with that idea. A bullet coming out of a shorter barrel travels slower because the propellant gases have less distance to push against it. and a slower bullet hits with less energy, which means a less armor penetration, which is the entire point of an anti-tank rifle. So, they had taken a rifle that was already struggling to get through German armor and made it even worse. The result was a weapon that was somehow even more painful to fire because the muzzle break was gone and that couldn't actually penetrate the tanks it was meant to fight. The MK saw its main combat in Tunisia in late 1942 with the first parachute brigade. On the 29th of November 1942, Lieutenant Colonel John Frost dropped near Deppen with the second parachute battalion, hoping to grab the Alna airfield and link up with the British First Army. But the link up never came because the First Army was halted by heavy German resistance and Frost's 530 men ended up isolated 50 mi behind enemy lines. German tanks attacked the paratroopers and the airborne boys rifles were now expected to do the work, but they simply couldn't. What happened next was the kind of nightmare that got the weapon retired permanently. Frost's battalion had to conduct a fighting withdrawal across miles of hostile ground with German armor and Stooka dive bombers coming at them from every direction. By the time the survivors reached Allied lines at Mees Albbab on the 3rd of December, a few accounts mentioned boys gunners watching their rounds bounce harmlessly off German tank armor, then having to abandon the rifles and run.

[00:08:24]The shortened airborne boys had proven completely useless in Tunisia, exactly like critics had warned it would be.

[00:08:29]Now, there were still some scattered moments where the boys actually provided some value. In the rocky western desert, British infantry would fire.55 rounds into stone outcrops near hidden enemy positions because the rock splinters would cause casualties even when the bullet itself didn't hit anyone. The seventh Huzars knocked out five Italian CV light tankets in a single engagement because those tankets were so thinly armored that even a stiff breeze could probably damage them. But these were tiny winds in a much bigger story of failure. And by the time Tunisia ended, the British army had decided enough was enough. The replacement had actually been in development since 1941 when British weapons designer Major Milis Jefferus picked up an earlier project called the Black Bombard and turned it into something genuinely useful. The result was called the Piet and the letters stand for project infantry anti-tank and it worked on a completely different principle from the boys. A regular boys would fire a high velocity bullet from a long barrel. But the Pat used a heavy spring and a thing called a spigot to launch a 2.5 lb bomb with a hollow charge warhead. You see, a hollow charge doesn't work by speed at all. It instead uses a cone of explosive that focuses its blast into a thin jet of molten metal, which can punch through almost any armor it hits, regardless of how slow the projectile was moving when it got there. So, a hollow charge bomb traveling at maybe 250 ft per second from the Piet could go through about 100 mm of armor, while a boy's round at over 2,900 ft pers could barely get through 23. The Pat first saw service with British and Commonwealth forces during the Tunisia campaign in early 1943, and it was an immediate upgrade. It could knock out almost any German tank in service at the time if you hit the right spot. And it had no back blast at all, which meant you could fire it from inside a building without giving away your position. And just like that, the boys was finished as Britain's main infantry anti-tank weapon. By 1943, around 115,000 pets were ordered, and the boys was being pulled out of frontline European service as fast as Piet could replace it. A total of six British and Commonwealth soldiers ended up earning the Victoria Cross the highest possible award for using the PR in combat. And not a single Victoria Cross was ever awarded for using a boys.

[00:10:42]The boys did keep going for a bit longer in the Pacific, where Japanese tanks like the Type 95 were still light enough that the rifle could actually hurt them.

[00:10:50]The first Cambridge SH regiment claimed the boys was useful for punching holes in walls during the Battle of Singapore and the US Marine Raiders bought a few hundred of them for jungle fighting. But even there, by 1945, the M2 Browning 50 caliber machine gun had largely replaced it because the Browning could do everything the boys did and put hundreds of rounds downrange instead of one shot at a time. In total, around 114,000 rifles were built across all the variants by the time production stopped in 1943. But a few even popped up later in some really strange places. The IRA used the boy rifle in 1965 to disable a British Navy patrol boat called HMS Brave Border by shooting straight through the hull and into one of its turbine engines. A few were used by Israeli forces during the 1948 Arab-Israeli war. After the Korean War, the US Marines borrowed some boys rifles from the Canadians, strengthened the action, mounted scopes on them, and used them as experimental longrange sniper rifles, firing modified ammunition.

[00:11:50]These rifles could hit targets out past 2,000 yd, which was actually pretty impressive. But it was way too late. So, the boys went down in history as the anti-tank rifle that arrived just slightly too late. Captain Boy himself never lived to see his weapon either succeed in Finland or fail in France since he died before it was even in service. And by the time the war was over, the entire concept of the anti-tank rifle was finished. Since these hollow charge weapons like the Pat, the American bazooka and the German panzer fast had taken over completely.
