Watch as Full Mag Youtuber fires a Finnish Lahti L-39 anti-tank gun at 16 1/4 inch steel plates spaced out between 4 inches. Using armor piercing Tungsten rounds to see how many steel it can punch through. The weapon utilizes skis and a special bipod to stabilize the recoil.
The Lahti L-39 is a Finnish 20 mm anti-tank rifle used during the Second World War. It had excellent accuracy, penetration and range, but its size made transportation difficult. It was nicknamed “Norsupyssy” ("Elephant Gun"), and as tanks developed armour too thick for the Lahti to penetrate its uses switched to long range sniping, tank harassment and with the L-39/44 fully automatic variant, employment as an improvised anti-aircraft weapon. See this 20mm anti-tank gun in action and read about its history here.
Ah want wun!
Impressive. But I find it strange that the article leaves out any mention of Chuck Norris.
Stacked one after the other, 16 plates x 1/4”ea = 4”. The photo clearly shows space between each plate so that’s more than the 4” purported by the article. The key to any armor system’s performance is the changing material characteristics in the armor “sandwich.”
20mm Anti-Tank Gun vs 16 Steel Sheets

About that title:
How come they didn’t place 50 of them 1/4” sheets on the fixture?
Then the article title could have read with a more impressive-sounding
“20mm Anti-Tank Gun vs 50 Steel Sheets!”

The Lahti 20mm Anti-tank Gun: The ‘Finnish Boombeast’

“With an 1800-grain armor piercing high explosive bullet moving at 3000fps, it generated 35,543ft/lbs of energy at the muzzle. When you keep in mind that the .50 caliber BMG round popular in the Barrett rifle and M2 ‘Ma Deuce’ brings 13,910 ft. /lbs of energy with a 660-grain bullet, you can see just how brutal this round was.”

Yep, that will get er done. And with the original ammo, imagine the increase in penetration.
Of course with todays armor on tanks? Not effective.
A little sports catalog called: YE OLD HUNTER sold the surplus behemoths for 99.99 complete with skis. The ammo was 2.50 each. My parents wouldn’t let me get one and I was too young. Not everything guys need has to be practical.
They probably thought you’d shoot your eye out with it.
Have the swedes figured-out how moozlums this will go through? Just askin’.
It was poorly written, but I think the author meant 16 one-quarter-inch steel sheets spaced at four inches apart.
How do you pronounce that?
“The photo clearly shows space between each plate so that’s more than the 4” purported by the article”
Let’s assume you walked into Abby Sciuto’s lab with this picture, she’d probably give a spiel something like this:
The photo does show the spacing, but the photography leaves much to be desired. Nonetheless, the photo can be imported into a CAD program and using simple photogrammetry, the distance between the plates can be measured.
Plates 7 & 8 are the best subjects to use as their position in the optical field of view gives less distortion.
Assuming they are 1/4 inch plates, the spacing calculates to 3.39”. However the poor lighting distorts the actual thickness of the plates, so it 3.39” may not be accurate.
The spacers appear to be 2x6’s standing on edge. The nominal thickness of the “two” by six is 1.5”. Two side by side would be 3”, which is quite close to 3.39”.
Therefore, the safest assumption with this poor photography, when imported into a CAD program and measured, is a spacing of 3”.
(sorry, not picking on you on purpose, photogrammetry is something I do, and thought of it before reading your post)
Enough practice! Turn it on the islamists.
At one of the classroom buildings at Fort Knox, there were display cases in the hallways, featuring thick slabs of metal with holes in them. Amazing, and frightening at the same time.
Sometimes I go to the USS San Francisco Memorial above Land's End in San Francisco. The memorial includes a damaged section of the auxiliary bridge removed after the battle of Guadalcanal in 1942. There are gaping shell holes where Admiral Callaghan, Captain Young, and most of the bridge crew were killed during the battle.
I always get a little lump in my throat when I see that. That action was November 12, 1942 - less than a year after Pearl Harbor. Nothing was certain, those men went into battle and died in a fiery hail of steel, not knowing whether it was won or lost or whether the United States would prevail. But they gave all. After that battle the Japanese could not reinforce Guadalcanal and the Allies moved down the road another step towards victory over tyranny.
Sometimes I just stand there and look out to sea and wonder, could I stand there and do my job despite knowing a slice of hell is headed my way? Is it even sane to wonder about it, because should the time come would a moral person really have a choice to act otherwise and if fear takes you would you even be able to make a choice? I touch the edges of twisted metal and wonder how could anyone want such a thing to happen again? I pray it won't come to that, though I know it's not really up to us...It's as close as I come to praying these days.
