Subject: [SG] GMS variants (NO ITS NOT MORE VACC-HEAD STUFF)

To briefly take our minds off the ceaseless fighter argument... (*grin*)

I was thinking about GMS systems and what they can and can't do in the
Tuffleyverse, specifically in SG2.

What we don't seem to have:

- Laser designation (or the equivalent) for GMS/arty/DFO (though we do,
oddly have figures)
- Over-the-horizon (OTH) (or whatever you'd call something that can
launch an attack out of LoS) capabilities
- Active emission homing missiles (like a high-tech HARM)/artillery
round/DFO load
- Off board GMS (cruise missiles?)
- Programmable attack GMS (to hit weaker sides of a vehicle such as top
or rear)

Now, me an Allan have been discussing some of these. I've taken a first poke
at the Laser Designation part of things (trickier than it looks). But what
about the other areas?

OTH missiles would probably need the designation rules, though possibly not if
they were real smart. They'd be launched with maybe a GPS targeting solution
followed by having a homing head (to pick up 'painted' targets) and maybe
another stage of visual or signature based target ID in the even no
designation was present.

HARMs or the like could actively target any unit that had communicated
(possibly) or any ACTIVE EW unit or unit using active sensor suites (GSR,
etc). This would insert into the game a DARN good reason for EW units to
consider being inactive, or moving around a lot.

Off-board GMS might appear as heavy rockets, but might be considerably
more accurate. They also might have a multi-level targeting capability -
designator, signature/visual, GPS coords.

Programable attack GMS are probably quite feasible, but what kind of PDS or
other penalties should appear due to the altered attack profile, if any?
Should the missile miss more often?

Looking for some discussion from those who might know, or failing that have an
opinion sufficiently advanced that I find it indistinguishable from magic.....

Top attack missiles.

Since these puppies exist anyway then they probably ought to be represented on
the SGII battlefield.

Lethal against open toped! IIRC top armour is one level weaker than frontal
slope armour, DS II page 10.

Maybe GMS/L or H only?

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

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.

The arc flight path is slightly more vulnerable to PDS.

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

You need to look at my Nasty weapons in Dirtside page....

Active Radiating units would be CBR and ADS that are active. Everything else
is too difficult. Command posts would have multiple emitters that are placed
remote from the CP as would most other basic comms type units.

GMS that resolves like Artiller for the designated stuff. Missile Launches,
red force activates a unit, blue force designates and
resolves attack. Given the general type, this would always be a GMS/H.

It'd be coming in like it's hair was on fire and on a ballistic path.
Once it's on its final arc, getting it stopped with ADS/PDS would be
hard. It's still going to hit and it will be landing on the top armor. Some
design work has been done on Kinetic energy guided missiles. A copperhead,
Hellfire, or Maverick landing on top of your

Which is why you wait. The profile of things like Copperhead and Hellfire
allow for a delay and no lock on before the launch and boost phases.

But a larger top attack missile is bigger and heavier. You've got the greater
issue of the missile is dead but it's still going to smack in to you. That is
the great issue with supersonic ASMs. You have to kill them further out since
the engagement time for the PDS is so short and has such a low effectiveness
level.

G'day,

What happens on planets with no GPS? How quickly would GPS be set up?
