We don’t have these in the UK we have potholes 😂

Cheap to manufacture, doesn't need high qualification workers, easy to deploy, no risk to engineers in the field, easy to recover, not a danger for post-war life like anti-personnel or anti-tank mines are.

Monty Python posed the question in Life of Brian: "What did the Romans do for us ? " Now we have another thing to add to the list... Brilliant

The trick is that the needles are hollow and it allows the air to rush out. The solid needles are less effective

As an Army engineer, I made it a point to teach armor about concertina. It is far more effective than you might imagine, binding tracks and drive wheels to bring the tanks grinding to a halt and requiring hours of maintenance to undo.

If it ain't broke, don't fix it.

Folks in the Western US still use caltrops to keep hunters and fisherman from trespassing. Or at least getting very far in their 4x4’s and ATV’s. They are cheap and easy to make.

We always think that technology is the answer when we might already have all that we need. Thank you for sharing this! Best of luck to the Ukraine!

"If it's stupid, But it works, Then it isn't stupid"

Without even watching the video, I'm going to guess that the weapon is caltrops. A weapon used by the Romans and Medieval armies to stop cavalry and even infantry charges.

Everything old is new again, just like clothing...

Quebec roads inflict far more damage and not only to the tires.

I thought you meant turning the road signs round the other way to totally confuse the enemy

Abandoned by the Romans when the Visigoths developed run-flat tyres on their chariots.

Didn't James Bond use them from his car?

The old tricks are the best tricks😂

Used caltrops in Northern Ireland during op banner a smaller version carried in flat metal boxes could be pulled across the road quickly if needed

It's so useful it make the Russian retreating Forward.

Slava Ukraini!

Just goes to show that sometimes the simplest ideas are the best.

Next, they will be talking about bronze-age weapons such as knives.

How did I know it was caltrops before even clicking the video?

So, I used to play a vocab game with someone until I brought up caltrops and they quit lol. They were used to maim horses and slow cavalry in the bronze age. Now, same concept except vehicles are the modern cavalry.

I've seen many of those. When the coal miners were on strike in the seventies in southwest Virginia, the strikers would scatter those on the roads where the coal trucks didn't stop hauling to support the strike. They were very effective.

the progression of better mouse - better mousetrap is not linear, and sometimes the old mousetrap works on today's mouse

Zoomers discovered anti-tank hedgehogs, but smaller ones

In America the police call them a spike strip. It is used to stop vehicles that the police are chasing.

When are we going to see the trebuchet drone?

Added to pile of game changers.

Funny how they all are attached by a chain so they can remove them with a bmp or tracked vehicle, or in some cases by hand given a couple minutes, them shining in the light dont make them very stealthy

The cartels have been using those in Mexico for decades.

The Romans had caltrops with barbs on the spikes, like fishhooks...

Caltrops have been in continual use since the Greeks. They were used against cavalry until the modern age. Infantrymen would seed the field in front or throw them into the path of oncoming horsemen, and they have been used in the twentieth and twenty first centuries against soft wheeled vehicles, often dropped by cluster bombs. There are many clever designs. Home made ones were widely used against the Germans by resistance groups in Europe who quietly placed them on roads by hand. The games that little girls used to play called "jacks" with six pointed stars and a rubber ball are miniature versions, and in the seventies oversized ones made of heavy metal were popular as book ends in the United States.

I love that spiral clock at 0:52

Im really amazed the Russians are not using run flat tires by this point

Stop Sticks on a chain. Plywood with 16 penny framing nails works wonders too, and very easy to throw leaves and dirt on it, and hide it on a dirt road.

Caesar employ them outside his fortifications during the battle of Alesia , it slowed the charge of the Gauls!!!

The Japanese word for Caltrop is Tetsubishi which means iron diamond . Many times in Japanese history a cavalry charge has been blunted by sowing tetsubishi on the battlefield .

I'm kinda relieved Ukriane is on our side now, they are some ingenuis bastards when it comes to warfare lol.

I used those to keep my wife out of the TV Room when I was watching sports. She wised up & swept them aside with a broom. (as vehicle drivers learned to attach angled brushes to their vehicles to sweep caltrops aside) I finally learned to eat chilli or cabbage before a sporting event. That kept her the Hell away.

"Lazy Tom's" where used in Northern Ireland at vehicle check points. By the British Army. They were also taken on patrols for use in random check points. These were a piece of chain with spikes through it. They were quite heavy, and so they would be cut in half. The result was then known as" half lazy Tom's". Ingenious!

In my country we call them : Miguelitos, older than injustice.

The hollow tube ones will cut a plug out that no self-sealing tire can possibly counter.

Some ideas never get old.

i can hear the war in the air

What the Romans taught us - lots !

Ah my favorite item in D&D!

This is practical in so many ways crazy how effective an ancient technology is even in present day

Ive heard that the madagaskar navy uses these in their submarines…

Ukraine needs all the help that it can get.

Rommel had larger ones lining the shore on D-Day. They caused a lot of physical problems effecting landing craft and the Allies.

They could also be dropped by drones onto power lines and into sub-stations to short out the electrical network in Ruzzia.

Caltrops? Yup caltrops

Creativity is important...

Old is gold

I have 20 of these odd pyramid shaped devices and they certainly will pop a tire lol

When you're left with no modern weapons you do this

The art of war

Had those back in the 80's Germany. Only problem was getting them deployed. Was a pain.

This is so genius

Caltrops

Dont forget mud !!

War. War never changes.

Yeah, but all you need to do on a paved road is mount a deflector in front of the tires (that sits like an inch off the ground) and they're no longer a threat. Give it a bit of a spring and put rollers on the edges, and it won't even get damaged when the tire bounces down on the road. I mean, I'm glad that people are being creative, but this is only effective in the very short term.

So they won’t need the 61 billion $ after all?

Fascinating

Hollow tubes would limit escape by coring the tire instead of a slow leak.

Everything old is new again! 🤯

Ok so all russia needs is high powered magnet on front if tank to pick them up lolol

If they were using hollow pipes to make them, they would cause the tires to go flat more quickly

Smart, keep it up.

Caltrops. Used by armies for centuries. Until gunpowder.

They always act like this thing can stop the whole Russian advance when in fsct it actually can't.

Ivan Ivanovich Ivanovsky: "That's a good idea! Let's do that too!" Meanwhile, Ukrainians are already working on countermeasures.

Someone took the phrase "Going medieval" exactly the right kind of literally

They used them in Korea as well

they can't stop tank or APC with track

Ingenious!

Those Romans were smart!

Simple mais ingénieux.🇺🇦🇨🇵🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵 Bravo 👏👏👏👏👏

They just made themselves a mark..

Genius

Anyone who’s ever stepped on a Jack will attest to the brutal effectiveness of such a device!

LMAO This is why the US military has vehicles with airless tires/tires that can drive on the rims.

I'm sure this will turn them back, they'd never have come if they had known!

And we do not even know the name of the brilliant investor. His descendants should be proud that we still have use for his invention today.

CALTROPS! YES! Very dear to my heart; as I've studied sword, sheild and spear, and spent some time on a trebuche team. Cheap and effective! It's time we pulled a few very old reliable tricks from the history books. History nerds are pleased!

Caltrops we not first used by the Romans.

Daft war propaganda is pretty old hat as well.

I didn't know the Russians had Humvees @:51 Very interesting.

The Russians just keep moving forward I guess someone at Forces News forgot to tell them to stop when the Ukrainians put some trinkets on the road.

Welcome to the world of labor disputes in the Americas. Here they're called "Jack Rocks" and used to disable non-union vehicle traffic trying to cross picket lines or service companies experiencing strikes. Been in wide use here since living memory. Thanks for the drone tip, though. Will file that one away for later, LOL.

Just goes to show how rock-solid ancient ideas were.

Wow, the Romans were clever. Concrete, aquaducts, and stadiums. Glad the Ukrainians used these easy to produce spikes so effectively, and easy to pick up later, unlike landmines.

It's not new or reborn,😂 used in all wars , Bosnia I remember them, Iraq etc. Heads up I heard they're using an old caveman technique called ... Fire😂

Very smart

Congrats to the Ukrainians!

I see the Russian bots are still being "deployed"

Well, it depends what you mean by 'stopping', as in some areas they are rampant and Ukrainian troops are either refusing to obey orders or surrendering en masse.

So why are we sending them £ billions worth of missiles then?
