Hmmm sonic devices,

Well, to use a sonic device to cause real damage, you need something that
would resonate (vibrate at a specific frequency); this way the maximum sonic
(kinetic, but sonic sounds cooler) energy eventually casuing problems for
the crew/holder, and eventualy breakage.

So you would need some way of identifying the resonant frequency. Being a
bughunter, I'm more thinking of; run up to a tank attach sonic clamp mine,
run, watch the fun. As resonsnce is reached the crew go deaf and eventually
the tank ruptures (possibly after the magazine goes off
:-D ). the only defence I can think of is sufficient dampening to
[prevent
resonance occuring, or to have all sorts of different parts of said AFV having
different resonant frequecies (I believe that some cars today boast this as a
feature (?).

Those are my thoughts, what do you guys think?

Some problems:
- Attaching the mine
- Keeping it attached while it shakes the tank to little pieces
- Supplying enough energy to do the job - probably about the same as to
blow a hole in the tank
- Not as quick as an explosive mine.
- Countermeasures - electronical or mechanical to dampen or actively
countract the vibrations.

For most game types, probably not too different from other stick-on
mines.

1) If the small sonic device you use as a mine has enough juice to shake an
AFV apart, its batteries has more power per volume than the best high
explosives we're researching today - and much more than anything we
currently have in service.

2) If you've got that much energy at your disposal, there are *much*, *much*
faster (not to mention more certain) ways of taking out an AFV than to let it
slowly shake apart

3) All sorts of different parts of a vehicle *have* different resonant
frequencies. If they don't, the vehicle will be pretty intolerable to drive
due to high noise levels, and in bad cases even risks shaking itself apart
simply by driving around.

Or just ask lotus (the car people). They have designed a system that can be
fitted to cars that uses a set of microphones and broadcasts through speaker a
inverse sound wave to the incoming one that cancels the original wave,
resulting in peace and quite (or in another bit, could make even a ford 4 cldr
engine sould like a porche flat 6).

BIF (probably getting the terminology wrong)

But funnier! saves having to penatrate the armour, and possibly reusable too

but on the kiss principle, just shoot it!

I think I saw an episode of "Bugs" about this kinda technology, but took it a
bit further. I don't think I really believe in inverse sound waves, but hey,
its science fiction! I suppose as long as you know wha the frequency is, you
coudl generate inverse. But if the mine was switched off you'd shake yourself
apart (not good!)
