Real E.F.P.: Pocket-​​Sized Tank Killer

The pic­tures released last week of Iraqi high-​​tech explo­sives sur­prised me. These spe­cial ‘super­bombs’ that have caused so many US casu­al­ties — they look like they had been assem­bled in someone’s garage.
These bombs belong to a class known as EFP –‘Explosively Formed Projectile’ or ‘Explosively Formed Penetrator,’ depend­ing on who you’re talk­ing to. They com­press a metal liner into a slug and fire it at the tar­get some dis­tance away.
slam3.jpegThe pic­ture shows what a real EFP muni­tion looks like. This is M2 Selectable Lightweight Attack Munition (SLAM). It’s small enough to put in your pocket and weighs a cou­ple of pounds.
This ver­sion has been used by US Special Forces for the last 15 years or so. As GlobalSecurity​.org describes it, SLAM is ver­sa­tile, too:

It will be used to sup­port hit-​​and-​​run, ambush, and harass­ing, and urban war­face mis­sions. SLAM will also be employed by Light Combat Engineers and Rangers where mis­sions war­rant the use of such a device.…SLAM is light­weight, lethal, eas­ily emplaced, and can be car­ried in the quan­tity nec­es­sary to neu­tral­ize a broad range of targets.

Different modes allow SLAM to be trig­gered by the heat or mag­netic sig­na­ture of a pass­ing vehi­cle or by a timer — or it can be set off by a human oper­a­tor. It can be emplaced in sec­onds and spits out a lethal slug which can punch through 40mm of steel armor at a range of 25 feet. You can leave it on the ground cov­ered in dirt to attack a vehicle’s belly, or con­ceal it beside a road for side attack.
No doubt the Russians and Chinese have their own ver­sions of SLAM, and these have prob­a­bly been copied too. So you might expect a rougher, cheaper copy to appear in Iraq if it was sup­plied from the out­side.
But as has been observed here, any­one can make crude and sim­ple EFP muni­tions in a basic work­shop. All you need is a lump of plas­tic explo­sive and a piece of cop­per. Shape the cop­per into a saucer, put the explo­sive under it, and you’re there. Obviously this will be a lot less effi­cient, accu­rate and reli­able than some­thing like SLAM (opti­mal design of the the metal ‘lens’ is an art requir­ing a lot of com­puter power), but you can com­pen­sate by mak­ing it ten times big­ger if you need to.
Maybe the insur­gents should be given some credit for being able to build their own gear, or maybe there’s more intel­li­gence we don’t know. But if EFP mines were being sup­plied by an out­side source, you might expect to see somethng a lot slicker.
UPDATE 11:37: Speaking of sur­prises, Centcom com­man­der Adm. Fox Fallon doesn’t agree that the Iranian gov­ern­ment has been sup­ply­ing Iraq’s EFPs. He’s not alone. Joint Chiefs chair­man Gen. Peter Pace, on the other hand, seemed to back away from his pre­vi­ous, doubt­ing state­ments — at least a lit­tle. More here.
UPDATE 01:20: The bombs aren’t the only issue, of course. According to the Telegraph, Iranian-​​supplied sniper rifles are also mak­ing their way into Iraq.
UPDATE 02:24: Bush has no doubt.
UPDATE 15/​02/​07: Steyr, the Austrian mak­ers of those .50 cal sniper rifles say there’s no proof they came from Iran — and that they might not even be Steyr-​​made rifles at all.

    In regards to the Iraq War; there are many good rea­sons for leav­ing; but for me on sticks out larger than oth­ers. Second only to the loss of American lives for the stink­ing rag heads is the Bush bud­get. He is cut­ting every social pro­gram in the coun­try while ask­ing for more fund­ing for the war. So basi­cally we are pay­ing for this crap war by way of the most ven­er­a­ble Americans. A pres­i­dent and a gov­ern­ment should base all of their deci­sions on pro­tect­ing the most ven­er­a­ble of our cit­i­zens; instead we are throw­ing money at an Iraq gov­ern­ment who will even­tu­ally turn against us in the name of islam. What a pathetic for­eign pol­icy; a pathetic admin­is­tra­tion; and pathetic cit­i­zens who allow this type gov­ern­ment to exist. You want a solu­tion to the sit­u­a­tion in Iraq; ask yourself

    “GM FEDORCHUK: If you are a wacko right winger who’s t-​​shirt says “kill em all and let God sort it out”, you need to try read­ing the Bible. Or at least read “Battle Ready” by Gen. Tony Zinni USMC (Ret). You can learn from that true pro­fes­sional.
    If you are a left winger who believes that cut­ting and run­ning from Iraq is the right thing to do, wake up and smell the cof­fee. We threw that coun­try into a state of anar­chy. We either fix the prob­lems we jumped into, or we live with the cost of our fail­ure.“
    Mr. Fedorchuk,
    If you read the Bible, the OT for sure, you will get the same advice. Where the hell do you think that expres­sion comes from?
    – “Neca eos omnes. Deus suos agnoscet”.

    I think the big­ger prob­lem here is the fact that this arti­cle and the com­ments after basi­cally tell any­one how to make one of these. Why not show us some dia­grams? Would that make your arti­cle more com­plete? These things do some seri­ous dam­age and have already been in use tak­ing American lives ‘over there’. So how about cut­ting back on the ‘How To’ sec­tions and maybe putting some thought into your piece!

    The bot­tom line is what the Republican sen­a­tor com­mented in a recent speech. Our sol­diers are patrol­ing the same streets, the same way. Being blown up by the same bombs day after day. What does that tell you about the mil­i­tary stratagy.

    If some of the weapons are being copied you may want to see if CNC man­u­fac­tur­ing is being employed. Look for machine lan­guage pro­grams that pro­duce weapons com­po­nents. If you could obtain records from equip­ment man­u­fac­tur­ers that may have sup­plied high tech equip­ment you could locate poten­tial weapons com­po­nent sources.
