Networked Landmines Work Together

crazedpilot writes "New landmines will soon communicate via a radio network, and move from place to place in order to be most effective." Termed the "self-healing minefield", the individual mines are capable of detecting an enemy breach and then moving to seal the gap.

These fucking mines HOP.

I really want to know what happens when they run out of power though?

Are they inert or do they revert to a dangerous stepper?
The inert option would seem the best since they can be tended to for the duration of the war then afterwards no children will lose their legs or anything.

Re:Hoppers!

[Aquillion (539148)]

That's easy. When they get low on power and sense somebody walking nearby, they leap onto their face and inject a cache of minefield-embryos into their belly. Within about a day or so, the host explodes, scattering a brand new fully-charged minefield where the enemy least expects it!

When science gives us a self-deacivating minefield, or one that can distinguish a combatant from a civillian from a cow, then we'll have real progress.

Re:Hoppers!

[bunions (970377)]

Yes. I also concede that tanks, machine guns, mandatory military service for all South Korean men, nuclear bombs, Delta Force, Chuck Norris, and the prayers of innocent children have helped to keep North Korea from invading South Korea. That's the 'dichotomy' part of 'false dichotomy'. You can actually have no mines as well as not being invaded.

Re:Hoppers!

[bunions (970377)]

I'm not in the military. The people who are say that they're necessary

The NSA contends that nationwide wiretaps are necessary. That doesn't make it so.

I'm not going to be on the front lines anywhere and a minefield means that fewer of us have to be there.

That's an immensely selfish position, given the long-term civillian damage landmines have caused. I've been to towns in Cambodia where close to half of the inhabitants were missing limbs from old landmines. I'm given to understand that similar conditions exist in parts of Africa.

Actually, we DO have stocks of biological and chemical weapons.

Sure, they're "defensive" but let's be honest. Anthrax is anthrax.

The anthrax research is for a vaccine. In order to make a vaccine, you have to make some anthrax. To say the US 'stockpiles bioweapons' in an abuse of both words.

Re:Hoppers!

[bunions (970377)]

And every single injury is a tragedy. That still doesn't change the fact that in times of war, land mines allow the use of smaller infantry forces and result in lower casualties for the side deploying them.

Is this supposed to be the argument that convinces me that it's ok for anyone to deploy landmines? Because they're useful tools in the time of war? If it's not, please point me at it, because I don't see it. You know what else is a useful tool in the time of war? Killing POWs. I mean, hell, more troops are freed up to fight, so we should have fewer casualties, right? But we don't, because it's fucking BARBARIC. Just like landmines.

The last thing the world needs is more landmines

I'd be much more impressed if, rather than moving to seal a breach, they were capable of recognising the difference between enemy combatants and civilians who have wandered into the field (usually long after the war has finished).

Re:The last thing the world needs is more landmine

[by Anonymous Coward]

They do reduce civilian casualties.

But first can I say: holy crap! I was one of the main software engineers on this project (heck I still have the source code on my laptop) but that was like 5 years ago. NOW we get slashdotted?

In any case, the story we got was: normally, anti-tank mines are surrounded by anti-personnel mines. Anti-tank mines have magnetic triggers and are (relatively) safe for people: they are vulnerable to simply being picked up and moved out of the way. So the anti-tank mines are surrounded by APLMs to prevent the enemy from trivially disabling the field.

APLMs are the nasty ones that kill kids decades later. So in an effort to reduce the number of APLMs deployed DARPA tried this crazy idea of making self-healing anti-tank mines. in other words, since the anti-tank mines can protect themselves by moving, the anti-personnel mines are no longer necessary. And the world gets a little better.

This was a heck of a project to work on. I got to FIRE ROCKETS! Under software control! Super cool.

Re:The last thing the world needs is more landmine

[colmore (56499)]

I hope you're right. But I'm always wary of claims that new weapons will reduce human misery.

Look at non-lethal policing weapons. They haven't replaced lethal force, they've just allowed the police to weaponize conflicts they previously wouldn't have had weapons for: they can shoot first against a civilian demonstration if they aren't using bullets. I'm sure the people working on those projects imagined their technology replacing firearms. I'd be wary of working on any weapons project, no matter how rosy a picture the client painted for me.

Re:The last thing the world needs is more landmine

[geobeck (924637)]

I hope you're right. But I'm always wary of claims that new weapons will reduce human misery.

Case in point: A century ago, there were those who thought the airplane would make war obsolete because neither side would be able to plan attacks without the other side knowing. Then someone put a gun on a defensive plane to shoot down the reconnaisance planes. Then someone else put a gun on an offensive plane to shoot down the defensive planes. Then someone else said "To hell with reconnaisance; let's drop bombs on the enemy." ...and so on.

This strategy, while it means well, will probably lead to the development of anti-personnel land mines that attack approaching soldiers by homing in on the magnetic signature of their weapons... or the farm implement some poor soul is toting across the field after the war.

Re:The last thing the world needs is more landmine

[by Anonymous Coward]

I asked the same question; can't you just keep grabbing one at a time, wait for them to hop in, and clear it for you?

The answer was: the minefield is not designed to kill people, its purpose is to be an obstacle. The threat of deadly force, unfortunately, is required for it to be an effective obstacle. If you want to spend the next 6 hours fucking around with the minefield as if it's a toy while there's a war going on around you, you're not going to live long. A ranger who cleared mines for a living stopped by our demo site during one of our live-rocket demos and said, "If I saw this in the field I'd tell the unit to just mark it on the map and go around." Which is its purpose.

I'm not surprised, but still dismayed, at the "dude you're a monster!" venom that was unleashed at my original post. That's too bad. Was I uncomfortable with the project? Yes, a bit, and that was part of the reason I left the company. But I find it amusing that everyone on here claims to have such a clear-cut moral compass. "Don't work on anything that could possibly have a bad use" covers an awful lot of ground. Our SHM prototype used Linux; have you ever contributed to the kernel, and if so does that make you an accessory too? Why do you write open source software when some of it can, conceivably, be used for doing evil?

Re:The last thing the world needs is more landmine

In addition to the mines communicating with each other, the field commanders can communicate with the landmines to detonate them remotely once they are no longer needed.

I wouldn't. Civilians have no business wandering around a war zone. And you're supposed to clean up the minefield after you're done with it.

Detection

[Khomar (529552)]

Wouldn't a landmine that transmits a signal be relatively easy to detect? Just look for the signal and disable the mine. On the plus side, maybe these would make it easier to clean them up when the particular war that used them was over. There are many countries that are potted with landmines from wars that ended years ago. Taking a stroll in the country in these places is extremely dangerous.

Re:Detection

The goal of a minefield is not to be secret. It's supposed to be an obstacle which requires you know where it is.

Think of landmines as the modern version of a 3' fence a la Gettysburg. The field doesn't keep the enemy out or surprise him and blow him up; its purpose is to slow his advance to a crawl while he tries to clear the mines or avoid them.

And while he does that, your artillery and tanks blow him up.

Re:who supports land mines ?

[guruevi (827432)]

It's also nice to know that the US didn't sign it because most of those mines are made (and invented/improved) in the USA. According to Human Rights Watch, between 1969 and 1992, the country was responsible for exporting at least 4.4 million landmines to 32 or more countries. US landmines have reportedly been used in Angola, Eritrea, Ethiopia, Malawi, Mozambique, Rwanda, Somalia and Zambia.

The USA is also among the greatest stockpilers (4th in row) of landmines.

For those who say/think that the US doesn't use landmines: http://www.usatoday.com/news/world/2002-12-10-land mines-usat_x.htm [usatoday.com] => quote: The Pentagon is preparing to use anti-personnel land mines in a war with Iraq

For the USA it would be too much of an economic problem (for some people related to both Clinton and Bush) to ban landmines. Landmines are good for nothing. They are easy to deploy and cheap but hard and expensive to clean up and it is often not done properly or at all leaving a lot of innocent casualities long after. They are mainly used in the psychology of battle. A mine is not made to kill someone, it is made to disable soldiers and dishearten the rest of them that see it happening.

Re:who supports land mines ?

[by Anonymous Coward]

People bring this up to explain the US refusing to sign the treaty but it's not really a valid point. The US could, if it wanted to, do numerous things:

1)Stop selling mines to other countries(!!!)
2)Stop using mines unilaterally, except at the DMZ in Korea
3)Negotiate a waiver for the DMZ field

The first and second options are no-brainers, the fact that the US has not done either of these and is in fact developing these new mines is utterly disgusting. We stand with the scum of the earth when we stand up for the use of mines.
The last option would involve some kind of quid pro quo where the US kicks in some significant capital for mine removal, but we have no money spending billions per week in Iraq and mine removal will save a LOT of people from dying or spending their lives horrifically disfigured. Of course this will never happen since the warmongers at DOD resist all restrictions on what toys they get to play with, from mines to nuclear bunker-busters to White Phosporous to Napalm... is it any wonder the world thinks so poorly of us?

Sunset Clause

We already have ~way~ too many landmines, and way too many innocents being killed or disabled by them.

IF you're going to design a high-tech landmine, for heavens sakes, design in a renewable sunset clause so that if the landmine doesn't hear from you in 30 days it disables itself. If you need to reenable it, fine, but disabled should be the default.

Self-deactivating mines already exist

[phonicsmonkey (984955)]

Self terminating mines already exist in a much simpler version - a timed deactivation mechanism preset for the estimated end of conflict. The problem is that the failure rate, i.e., the failure to deactivate, is around 5%-10%. This makes it almost as good as nothing - would you want to plow a field knowing that "only" 10% of the original mines are still active? Cluster bomb bomblets, basically small touch-sensitive tactical mines, are even worse with an estimated failure-to-explode rate around 25%-30%. The only safe minefield is a non-existant one.

Self Healing?

[gillbates (106458)]

Since when to landmines heal anything?

An adaptive minefield would be a better term for it. They only "advance" this land mine possesses is the unique ability to be turned against friendly forces by a technologically advanced enemy. How would you like the land mines you planted hopping toward you in the middle of a fire fight?

As a former artilleryman, I can tell you that this would be close to useless. We were taught to clear minefields with artillery barrage - that is, when the first soldier encounters a mine, they all draw back and call in artillery. An artillery barrage will detonate all of the mines, regardless of whether they want to be detonated or not.

I never did like the concept of mines in the first place. They are the only munition in which a human is not involved in the targetting decision. Think about that - they'll kill anyone, or anything, indiscriminantly. U.S. mines will kill:

• Enemy soldiers
• Enemy vehicles
• U.S. soldiers
• U.S. vehicles
• Women
• Children
• Medical personnel
• Animals

Land mines are the only munition which stand a substantial liability of killing non-combatants. The aren't a humane weapon no matter how you think about it.

And this so-called advance really isn't an advance. Typically, when encountering a minefield, the infantry will call in artillery, which will detonate all the mines on the battlefield at once.

Re:Self Healing?

[dedazo (737510)]

• All mines are lethal and deadly. Even those designed to wound (yes, they exist) have an error margin (meaning they'll kill you anyway).
• There is no such thing as a "humane" weapon, unless it's specifically designed not to kill. There's no difference between a .45 hollow point slug to the head or a fuel air explosive. You're still dead. Perhaps you were thinking of scale or lethality radius.
• "US" mines will kill just as effectively as British, Russian, Chinese or Indonesian mines.
• Despite the much-publicized PR trips of famous people to victims of landmines in war-ravaged countries, landmines are still a valuable component of defensive warfare. There's a difference between using mines for clear military purposes and just sowing the countryside to see if you can kill a few kids. I'd really have the US continue to use mines in places like the DMZ than to have to rely on a larger deterrent force. Like it or not, landmines are very cost effective.
• I don't know who taught you that minefields should be cleared with artillery barrages. This has been a mistaken assumption since WWI. In the first Gulf War the US Army gave up trying to do that because the overpressure from a relatively large artillery shell would not reliably detonate the mines but instead generate cratering that made navigating the minefield even more dangerous. They even tried MLRS volleys to no avail. I believe current doctrine relies on a type of shaped charge ("bomb on a rope") that is fired from a special "gun" on a carrier vehicle over the minefield and is then detonated to create the breach. Failing that there's always the trench tool and lots of cojones.

Doesn't surprise me that new mines hae comms

[Realistic_Dragon (655151)]

The British Army are, I believe, required to mark out where minefields are and clean them up when they leave the area.

Obviously removing mines is a nervous business (unless you have one of the awesome <a href="http://en.wikipedia.org/wiki/Matilda_tank">W W2 style flail tanks</a>, which look like so much fun they should be illegal) and so being able to remotley disable them makes a great deal of sense.

When it's hacked...

[Lally Singh (3427)]

How about when a hacker starts sending bad "mine blown" messages to the grid, making the mines reconfigure? Maybe they keep detonating off each other, maybe they start all hopping (with some nice navigational hacking) back towards the ones who deployed them?

Re:Useful for post-war clean up too!

[arivanov (12034)]

Russians have a similar system which attaches to most of their tanks and BMPs.

The problem with these is that they are slow and hideously expensive to run (fuel, maintenance, etc) and works reasonably well only against antipersonnel mines. Even in that case it requires repairs and overhaul after it has detonated a few tens of that. If the mines are of the antitank variety it lasts even less before overhauls. In addition to that some of the antitank mines are now equipped with delayed fuses which detonate later or detonate after n senses (same as the German antiship mines of WW2). It is enough to sprinkle 1 or 2 of these per every few 1000 antipersonnel ones and you can no longer use equipment like this.

What happens when the mine "chooses" not be inactivated?

Nuke it from orbit. It's the only way to be sure.

True.

In fact historically true.

The Russians did this to the German destroyer fleet on 10/11th of Novermber 1916. The Germans were given a fake map with the corridors through the minefield defending the Finnish bay. They sent in a single destroyer to investigate which safely came back. After that they sent in a whole detachment which went in and the russians mined the exit behind them. By that time the end of the channel was also mined.

As a result the Germans lost 7 capital ships and had twice more heavily damaged which is one of their 3 biggest naval losses comparable only to Jutland and Falklands. An impressive testament to what "moving" mine field can do.
