A new type of IED
consists of "shaped charge", located under the road surface or at
the side of the road.
In these explosive devices, a cone (also known as concave) made of
copper is covering an explosive charge creating a hollow space in
front of and along the axis of the charge.
When the explosive is activated, the copper
transforms into a forceful jetstream of molten metal also known as
"plasma". This plasma jet easily perforates an unprotected steel
armor, hitting the surface at a speed of 8,000 meters per second and
extremely high pressure. 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 is still devastating against
softer targets. In both cases, the effect inside the target interior
can be catastrophic, especially if it ignites unprotected ammunition
stores, causing secondary explosions. Anti-tank shaped charges must
be employed with utmost accuracy (activation distance, and design
accuracy). Therefore, they are used primarily with buried mines, and
lightweight anti-tank weapons.
Heavier IEDs which utilize the heavy slug concept can be used with
roadside ambushes, detonating at a standoff distance from the
target, inflicting devastating effect and fragmentation on the
protected and light armored targets and their surrounding. To be
most effective, the shaped charge has to be detonated at the right
distance from the target. If it detonates too close to the steel
armor, an optimal plasma jet cannot be formed dissipating the
penetration effect. If detonated too far from the armor, the plasma
jet is already unfocused and partly spent itself.
