There’s been a few comments about head shots to deal with a body who is packing an IED.
Only how close is dangerous if that device goes off.
As a basic rule of thumb, within 50 feet (15 m) is the kill distance when a carrier detonates. If you are beyond that, you may get away with being severely injured.
Yet in a building or subway packed with people, it doesn’t take a lot of BOOM to cause devastation from the primary effects of a blast i.e. overpressure, flame, let alone intentional shrapnel damage and harm caused from building debris.
NOTHING is set though, it all depends on the quality of the explosive, the construction and content of the device i.e. bearings, wire, nails. The surroundings i.e. the fabric of the buildings, relative altitude of the device to you, if anyone is in front of you to absorb material and blast, and Mother LUCK!
Yet sometimes the “safe” distances quoted by the experts to keep everyone from harm may be unattainable (if not a bit fanciful).
As an example, quoting from http://www.respondersafety.com regarding stand-off and evacuation distances.
A Suicide Belt weighing 10 lbs (4.5 kg)
In a building the recommended stand-off range is 90 ft (27 m)
How the hell you can achieve that quickly in a building escapes me and, of course, it is totally dependent on the fabric of the building.
Outside they quote 1,080 ft (330 m).
To complete the series:- A Suicide Vest weighing 20 lbs (9 kg)
Internally the stand-off range is 110 ft (34 m), externally that distance is 1,360 ft (415 m)
At 330 and 415 metres, visually I couldn’t positively identify a body packer without a damn good scope and generally speaking your unassisted eye definition at those ranges is ‘variable’ to say the least. As an example
Feet Yards (m) Visual Features
300 100 (91) You’ll recognise a face
600 200 (183) You’ll just see a face
900 300 (275) You won’t be able to clearly identify hands
1200 400 (366) You may see large leg and arm movement
1500 500 (458) You’ll see them move but colour definition is lost
1800 600 (550) It’s moving, and apart from that, very little detail.
A head is about 6 inches (16 cm) wide.
Of course all you super shooters will achieve that 101% of the time at 300-400 yards.
I like to dream too.
At best, today, my average is 3 MOA.
At 100 yards (90 m) that’s 3 inches thus doable.
At 300 yards, 10 inches. That’s doubtful.
Only I’m still way sceptical at loosing off at ANY range as the IED could be triggered by a bullet’s impact, the subsequent shock of the fall, or a ‘dead man’s switch’.
Me thinking that some devices use home-brew explosives like TATP which can be very unstable.
You’ve also got three major problems to consider before taking a shot.
Isolating the carrier without prompting a detonation
Clearing everyone away without prompting the carrier to detonate
And putting decent cover between you and the carrier as you shoot.
All that takes time. Someone on a remote trigger would negate that.
So is all the B.S. about headshots actually worth lip service?
The premise behind the thinking is a central nervous system shot will prevent the carrier from detonating. Sounds great doesn’t it.
Right up until you consider what happens next.
