Subject: Lasers in the colonies

Okay, here's my counter arguments:

1) You comments about lasers and the power involved may or may not be right.
Obviously the US military finds the idea of a portable laser weapon very
feasible as they've got something queued up. Once, of course, the power issue
is resolved.

2) Foggy days will suck as will really dense atmospheres. In thin atmospheres,
the laser will work really well. The lasers lack of kick (hence high FP) may
well be a fine compensatory value.

3) You might think you'll remain functional with a 2mm hole burnt through your
head, but I have my doubts. At any rate, I heartily advise you not to attempt
to experimentally determine this.

4) The argument about a 2cm hole assumes that I don't drag the beam across you
or put it on a wider beam. I think temporary or permanent blinding plus a nice
third degree burn across a 4" wide strip of your head might put you out of the
fight. Burns hurt a lot. And blinding with lasers is quite feasible. (Visors
could maybe stop it - assuming it can't shoot
through them - but people often have their
visors up (or helmets off) when humpin' through the backwoods, even if they
had one in the first place.

5) The argument about a 2cm hole ignores the
explosive effects of flash-heating the water in
your cells. BANG! Can you say chunks blown out! OUCH! Probably quite
disabling.

6) Reflec or Ablat? Har de har har. Fine for a panzer (who'd hiding that class
5 GEV anyway), absolutely unlikely for anything other than PA and even then I
have some doubt. Think that perhaps armour that will reflect a laser will
perhaps have a _low_ chance of managing
stealth in any EM spectrum? I do. You _might_
be able to successfully layer it, but then again maybe not.

7) A laser might, as I mentioned, have other
settings to make it multi use - everything from
starting a fire, acting as a flashlight, being used as a LoS comms, etc. Can a
gun do that? Uhh... not by its basic nature!

8) Power: If I can put enough power into a single cell (hence no need for a
power for the weapon) to induce fusion for a DFFG, then I
think the laser problem is well and truly a non-
problem.

But this has devolved to just about as useful of
a conversation as the religion thread - it hinges
on the same projections about what might happen. Since it is an entirely
conjectural event many many years hence (who in 1820 would recognize today's
world?), we're into the realm of "might as well do what you want and PSB it
because you're probably wrong..... but then so is everyone disagreeing with
you!".

Ah, you are counting on holes in the HEAD. I prefer
my soldiers able to incapacitate by hitting head/
arms/legs/whatever.

If the spot turns to steam you have pre-made ablative
armor as the steam blocks the beam.  I'd _much_
rather have a cauterized 1cm deep hole in my chest than have a 7.62mm piece of
lead hit the front and a 3cm piece of expanded lead leave the back. (Yeah, I
know the lead isn't 3cm, but the hole certainly looks like it is.)

And the implications of what I'm saying don't preclude a laser that works and
can kill people. What they do preclude is a battlefield with tanks and air
support. The laser that can chop a person in two can do the same to a tank or
an air vehicle at LOS ranges. The big targets don't stand a chance.
