Los thoughts on breaching

Carlos said: 

I was just thinking about how easy it was to breach walls in our FMA
game
with standard grenades while the guy is standing their pretty much in
the
same room watching. The physics of explosives preclude being able to do
that
unless you have a specialist shaped-charge or a huge mongo grenade that
will
kill anyone within proximity even the breachers. Ands I don't think a
secured underground scientific facility like the one we were fighting in
would be made out of sheetrock.
============================================
In actual fact, the HEAP grenades probably would have punched holes in
the
walls, but it might have been a melon sized hole... (but it never
happened).

The only two breaches made (man sized) were made by a dedicated engineer
figure with breaching charges to hand... he blew through two walls with
a
tamped explosive. Despite the fact I may have said grenades could
breach, we
never actually did this and you are right that it probably is
unreasonable.
Do I beleive you could make a "breaching" grenade? You bet. Rifle
launched... not thrown, though if you had something like a 5th element
grenade with a spike that would stick into the wall....

And I'm with the other guys who say that civilian construction is done
by
the cheapest bidder most times (so is some military construction).
Myself, I
think I could breach the wall in my office barehanded in about two
minutes
(might break a toe or some knuckles). Give me a crowbar, and I bet I
could
be through the wall in 60 seconds. (Admittedly, it'd be a serious
effort).
Would all places be like this? No. 

Would training facilities? Some. Would offices? Most. Even in secured
installations I've attended, with TEMPEST shielding and a minimum Secret
or
Top Secret to enter, many times the outside walls are fortified, but the
inside walls look a lot like my office wall. Around server rooms and
such
they usually have cinderblock, or in other spots stuff is locked up
which is
classified, but many of the other walls were drywall, gyprock or
plaster. 

Aside:
Nanotech might make a spray (or a spray grenade) of stuff that eats
<insert
wall material> or a simple chemical that disassembles it on the
molecular
level (accelerated decay). This would make an awesome breaching tool. It
might be available to engineers in a flamer-like spray dispenser... a
quick
blast and wait 30 secs and you have a man sized hole...

Aside:
Also, I might suggest that, if you like TDX, it would be possible to
build a
gravitationally polarized explosive and use it for some VERY nasty booby
traps (chop PA in half...). You might be able to use this type of tech
to
make a breaching charge. 

I can see we're going to have a lot of fun compiling our "FMA:CQB-2183"
supplement....
