That makes it five votes for no rounding and none against :-)

That's what it ought to be, though I'm not entirely certain what the
electronics mentioned in the quote above are supposed to do :-/

The "less worthy candidate" preferrably being an empty patch of dirt,
rock or something else you don't mind having blown up <g>

In extreme cases (EMP pulses, including radar - though ships are better
equipped to do this than tanks <g>) "ECM" systems could even destroy a
missile before it hits, but this could equally well fall into the PDS
category. Indeed, depending on what you mean with a "weapon" the PDS
description "Sophisticated sensor suites linked to fast-reaction
weapons, used for defence against incoming missiles" could include
chaff and flare grenade launchers as well as fragmentation charges,
rockets or cannon.

All the existing jamming systems I know anything about concentrate on
the link between the launch platform and the missile, with some working
against wire-guided missiles but not against beam riders and vice
versa... are there any jammers which work against Javelin (without
fooling the firer)? If there is one, I'd be *very* interested to know
how it works ;-) (...and whoever tells me any accurate data is probably
revealing rather sensitive secrets, too <g>)

At the moment ECM differs from Stealth but is very similar to PDS... Ah
well.
