Re: HEAT...Re: New 'electrical active' Armour to defeat hand held anti-tank rounds

Ryan:  You may find this a bit helpful if anyone questions the "plasma"
again.

First paragraph last 1/2, after the heading of Text:

  The 1940s saw the rapid development of High Explosive Anti-Tank (HEAT)
  shaped-charge weapons, which used an explosive-backed copper cone to
  melt through armour plate, using the focused energy of hot gas and
  molten copper or plasma. This had a dramatic effect on armour
  configurations and design, which has lasted for over 50 years.

If Jane's isn't good enough for you, there's many other references out
there, tell me what you consider authoritative and I'll supply the
reference.

Although, I do have to agree with the original cut:  
  "There is nothing "plasma-like" about the metal jet from a HEAT
round."
Frankly, there's nothing plasma-like.  It _IS_ plasma.

Ok, sorry to drag up an old conversation here. What is the jet from a 
shaped charge. What material state best describes it and it's 
characteristics?
