From the depths of my memory comes a reference to something called a THUDD (?) gun,
designed for making large holes in Battle Dress. IIRC it's basically a small number
of shaped charges on a string - the idea is that they will land and explode in
very short order on the same place. The sequence of explosions on a progressively
weakened area should penetrate armour of even a much high TL than the weapon.

Sadly, my Google searches have failed to turn up more than vague mentions (once I
ploughed through about a million links to what I think are World of Warcraft sites).

Can anyone enlighten me about this weapon? I'm not really after a gearhead definition,
more a description I can build on.
