I never knew that the shrapnel was sucked back in - I thought its momentum sent to outward only.
Very interesting.

SSG Matthew Hess, I always liked shaped charges.

Capt Seid Waddell - I worked with this system while I was at Eglin AFB, FL. To see an entire dispenser open and attack a column of tanks was truly devastating. Kick Ass! LOL

TSgt David L., I worked on the military land test ranges at Eglin, somewhat before these had been developed. Were these tested on R-52?

The videos I have seen of these were quite impressive.

I do... The best training I ever attended, was the Security Design course conducted by the US Army Corps of Engineers, which teaches you haow blast waves actually act, and how to mitigate them via proper security construction measures. CPT (Join to see)

From the science dude. Think about it from energy. First a gigantic release of energy that creates high pressure, heat, sound. That energy is projected out in all directions (like a ball or sphere) . But then, IF the explosive is big enough, there is an extreme low pressure valley created in the center. That causes the backwards wave. This happens in any explosion that is exothermic(releasing heat and energy). There is a great video of an atomic blast where the pressure wave makes trees go forward and back ahead of heat wave.
