One of these,great slo mo vid of it in action
and heres an animation of one being formed
The iranian toophan 7 is very similar to the us tow 2b/2b aero,this uses downward pointing explosively formed perpetrators to strike the top of the turret,the big advantage here is that the 2 efps take up a lot less room than a normal heat warhead which is a conical shape,the efp is a flat plate.
See the flat nose on the 2b just like the toophan 7?
Heres a diagram of the 2b,the iranian toophan is virtually the same,
Heres the earlier toophan 3,it looks virtually identical externally to the tow 2b but only has one efp.
