Side note: Lasers will be blatantly obvious to any SF force with optics.
Anyone not using the Mk I Eyeball will be able to tell what's being designated
and who's designating.

1) Can optics be set in all frequencies at once, from IR through visible and
out into UV? Dunno. If so, you're right. I assume designators will in fact
incur this risk. One of the parts of the rules is the idea of suppressions
applied to the designator or smoke (aerosol) laid to block the beam. I'm
assuming designators may be tunable and you'd have to have your optics on the
right frequency. And you hope they have good
amplitude cut-off limiters or I'm gonna maybe use your use of freq
filters to try to blind you...;) (Note CF personel have already suffered these
attacks from Russian spy ships) 2) I planned to lay down 'paint' counters. 3)
Maybe I can use some quantum designator or neutrinos or some thing? Dunno.
Something harder to detect.

One question:
Anyone (OO?) know how good/accurate a modern warner system is on AFVs?
Does it give you range/bearing and automatically undertake defense
measures? If so, what are the range/nature of responses?

> Programable attack GMS are probably quite feasible,

Didn't we argue over that already? Short Form: it depends on whether you're a
ballistic arc up and then
down, or a "pop-up" style attack.

[Tomb]
Assuming I wast talking only about top attack, yes.

I've never heard anything that indicates top attack missles are less acurate
than straight flying missles.

[Tomb] Here's my thought: If I try to get fancy and land on your back
deck, and you are moving, I have less margin for error than if I try to land
on the turret top or vehicle center. Similarly, if I fire a missile at you
from the front and want it to go around the side or back... well, that might
degrade accuracy. Maybe not?

Then again, my two main data points are the Javelin and the Dragon, and
frankly the Javelin could have a
50/50 chance of completely dudding and still be better
than the Dragon.

[Tomb] Well, we rarely see this kind of thing represented. Maybe for
ammo-tracking weapons, dudding (double 1s on the attack dice? or higher
for crappy weapons?) might be useful. Of course, you can PSB high quality in
2183, but I have as much faith in that as I do in honest

You could assume that while Snuffy is looking around in a certain narrow part
of the spectrum, his helmet is scanning and certain narrowly defined
parameters (ie: any precisely straight line of more than X length) will cause
it to warn him.

It gives you bearing, but range is difficult to analyze from a point reading.
You'd have to make assumptions about signal strength and that's sketchy.

Tanks move at maybe 30mph, missles at several hundred meters per second. In
the last second or two of
flight (when a pop-up attack would be executed) it
won't move enough to really matter.

[Tomb] Tracklayers yes. Perhaps Grav
Tanks, VTOLs, and AC tanks may move considerably faster. This might suggest
that there should be difficulties targeting faster vehicles. Perhaps evading
already covers that.
