    Description
    The M2 selectable lightweight attack munition (SLAM) is a multipurpose munition with an anti-tamper feature. The SLAM is compact and weighs only 1 kilogram, so it is easily portable. The SLAM is intended for use against APCs, parked aircraft, wheeled or tracked vehicles, stationary targets (such as electrical transformers), small fuel-storage tanks (less than 10,000-gallon), and ammunition storage facilities. The explosive formed projectile (EFP) warhead can penetrate 40 millimeters of homogeneous steel.

    The SLAM has two models -- one is self-neutralizing (M2) and the other is self-destructing (M4): The M2 is solid green and has no labels, brands, or other distinguishing marks. This device is used by SOF and is not available to other units.
    The M4 is green with a black warhead (EFP) face. This device is normally used by units designated as light, airborne, air assault, crisis response, and rapid deployment.
    The SLAM has four possible modes of detonation--bottom attack, side attack, timed demolition, and command detonation. Bottom Attack: The SLAM has a built-in magnetic sensor, so it can be used as a magnetic- influenced munition against trucks and light armored vehicles. It can be concealed along trails and roads where target vehicles operate and can be camouflaged with dry leaves, grass, and so forth without affecting EFP performance. Mud, gravel, water, and other debris that fill the EFP cup have minimal impact on EFP formation and effectiveness as long as the debris does not extend beyond the depth of the EFP cup. The magnetic sensor is designed to trigger detonation when it senses a vehicle's overpass. For the EFP to form properly, it needs a minimum of 13 centimeters from the point of emplacement to the target. The bottom-attack mode is active when the selector switch is set to 4, 10, or 24 HOURS and the passive infrared sensor (PIRS) cover is in place. The SLAM will self-destruct (M4) or self-neutralize (M2) if the selected time expires before the SLAM is detonated by a vehicle. Side Attack: The SLAM is equipped with a PIRS that was specifically developed for the side-attack mode. The PIRS detects trucks and light armored vehicles by sensing the change in background temperature when vehicles cross in front of the PIRS port. The PIRS is directional and aligned with the EFP when the device is aimed. The side-attack mode is active when the SLAM selector switch is set to 4, 10, or 24 HOURS and the PIRS cover is removed to expose the PIRS. The SLAM will self-destruct (M4) or self-neutralize (M2) if the selected time expires before it is detonated by a vehicle. Timed Demolition: The SLAM's built-in timer will trigger detonation at the end of a selected time. The timed-demolition mode is active when the SLAM selector switch is set to 15, 30, 45, or 60 MINUTES. In this mode, the magnetic sensor and the PIRS are inoperable, and the SLAM will detonate after the selected time has expired. Command Detonation: This mode provides manual warhead initiation using standard military blasting caps and a priming adapter (Figure 4-7). The command-detonation capability bypasses the SLAM's fuse and safing and arming (S&A) assembly. The SLAM has an anti-tamper feature that is only active in the bottom- and side-attack modes. The SLAM will detonate when an attempt is made to change the selector switch's position after arming.

  2. What is the point of this?
    SLAM has been around for a wile, I still prefer the Gammon grenade.
     
  3. Some flaws in the article you linked:

    No such thing as the Celtic Sea.

    PIR was not used by the IRA or any IRT groups. The IRA used active IR and abandoned it after a couple of failed attempts.

    PPM were the first to use PIR in NI.

    EFP and Shaped Charge are not closely related. They are two different types of attack.

    Nice piece of kit mind. Can't see much use for it in Iraq/Afghan, as coalition forces are not experiencing contact with vehicle convoys. Its employability as anti personnel (i.e in lieu of claymore) is somewhat limited.

    There seems to be alot of fuss over the possibility of Iran supplying off the shelve models. This would seem strange as EFP's are relatively easy to make and would not require bringing in from other countries.

    I have tried to avoid answering your ignorant posts and stupid questions, on subjects that I post. The Band of Brothers post, being one that IMHO showed your profound ignorance.

    I guess it never dawned on you as a civilian, that the 'Band of Brothers' that one served in close combat with might just be the reason that one will not forget the ones that he/she served with in wartime (Combat) service with. The ones with the same experiences and nightmares, The ones you always miss, and wish you could re-live that time with your 'Band of Brothers.' No one, in your life, will be as close to you as they have.

    Your posts generally, show your ignorance of military subjects, stemming from your total lack of any military service.

    Your mates here on ARRSE have defined you as a civilian, with no military servicewho uses narcotics (Coke.) I think they are right! I wonder; however, why they let you get away with posting the crap you do.

    The Gammon grenade is just that a grenade of WW II vintage! To compare it to a SLAM is really ignorent and again hows your lack of military background, etc.

  5. The British military does not use anti-personnel mines does it? And yea, as you say, there is little need for SLAM.

    Just a bit of humour, I was going by the way that SLAM is not exactly needed. Anyway, just because the Gammon bomb is from world war two, does not mean it is not worthy of use. Look at what weapons the US military uses, for example the USMC uses the M16, how old is that!
     
  6. Claymore (and munitions of this type) is not regarded as an anti-personnel mine and is not in contravention of the Ottawa Treaty.

    Just more ignorance on your part! When are you going to wise up and STFU you ignorant twit! :pissedoff:
     
  8. Not so, you evidently don't sail

    I too think this
     
  9. I don't find how you see my post as ignorant. I think you are going to have to wise up and shut your gob yourself.

    You mind liking me to the 'Band of Brothers' issue, I am sorry that I have missed your obviously imortant post.

    Do we use these type of munitions then? Would the layer of the weapon need to be a specialist too, like an Assault Engineer, I remember this specialisation includes mine warfare, I just thought it was solely Anti-Tank mines.
     
  10. No its not worthy of use, the No247 (Allways) fuze is very dangerous, it would quite often function as the user was attempting to throw it, and contrary to it's common name it didn't 'always' function.

    You'll be wanting No80 greanades back next, fecking horrible things.

    I suggest you nit-pick with the source of the articles!

  13. Granted that the 'always fuse' is a liability. But to fill the thing with anything you wanted (and the two sticks of explosive you get with it) would be useful in certain situations; I am not going to defend the thing though as you could do the same with a sock and a fuse, a wãnk sock would add to the amount of shrapnel :pissed:

    I think you need another 'quick fix,' with your favorite narcotic. You are a real POS! The more you post the deeper in shite you get! You put most 'Walts' to shame!
     
  15. You posted it as a source of information. That you had obviously read. I was just making minor corrections so that your were a correct, but i'm sure you didn't need the corrections as you do seem to know it all.
