What better vantagepoint to tell you of this, than from right here in my walled compound in Baghdad! Well! So, a concave cone made of copper is used to seal an explosive charge in an improvised explosive device:
Thia creates a hollow space in front of and along the axis of the charge.
When the explosive is detonated by a mobile-phone trigger, somehow “the copper transforms into a forceful jetstream of molten metal known as “plasma,” as the internet explains. “This plasma jet easily perforates ordinary steel armor, hitting the surface at a speed of 8,000 meters per second and extremely high pressure.” Some say that there is no armor in the world that can stop this plasma, though I have no idea. “If the plasma is not obstructed by a target within few meters, it solidifies into a kinetic slug which is less effective against heavy armor,” but short-range attacks, say, from a roadside trashcan to a passing vehile can inflict ghastly damage.
One of my colleagues here was killed yesterday by one of these while riding in armored civilian convoy. His guard team was all banged up, too, but they have already been released from hospital after removing shrapnel. Some spotter was waiting for the opportunity presumably, and dialed the bomb phone at just right moment. There were brief references on major U.S. news outlets yesterday.
The deceased was said to be pushing 70. He was an American who came to this small compound reluctantly for just a 5 day financial consultancy, and he was scheduled to fly out the next morning. It could have been any of us, on any day.
