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.

[Tomb] I don't believe this matches the
way CF EW units trained. They trained to be highly mobile because the minute
they went active, they started the clock on being located and destroyed. I
believe emission homing weapons were not
unlikely to destroy EW vehicles using mast-
jammers. Someone on the list who may have worked on an EW jammer vehicle may
care to comment on my perception. I would think GSR units might also be
destroyable this way.

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.

[Tomb] Today yes. It is quite possible to
envision a HARM GMS/P by 2183.

stopped with ADS/PDS would be hard. It's
still going to hit and it will be landing on the top armor.

[Tomb] Another modern day assumption.
DS2 construction rules make top armour far more effective than modern
equivalents (DS3 may allow you choice). Is there any particular reason the
2183 missile may target top as opposed to side or rear? Not that I know of.

Some design work has been done on Kinetic energy guided missiles. A
copperhead, Hellfire, or Maverick landing on top of your tank even with out a
war head isn't going to be good for the tank.

[Tomb] This hinges on the 8/3/1 ratio of
top/side/rear armour (or something like it)
that OO quoted. This is NOT the case in the DS2 construction system, which
suggests this threat has been analyzed and responded to by 2183 by upgunned
armour on the off facings (as the ratio in DS2 is
N/N-1/N-1). Therefore, although such off-
angle attack missiles are useful, they are not as big a threat as their modern
equivalent.

Otherwise every unit that called for artillery or what have you would be
targetable specifically.

There are a number of unique means of making Comms hard to DF/Jamm.
One is LOS lasers. Presumably you can bounce signals off of or direct them too
a LEO SAT right? Or you can lay fiber lines to a remote transmitter (multiple
units) by means of small drones that are expendable. A drone that would run
off to beyond the next hill and act as a laser repeater to another drone would
be easy. In this day and age we've gotten pretty good at figruing out where
something in the sky or ground is. In that day and age, I expect getting a
laser transmitter slaved to a very precise point will be trivial. Even on a
moving platform.

I don't care if it's better top armor or not. The point is that such a large
missile doesn't rely somely on warhead effects. Inertia and mass count for
quite a bit. A top attack weapon that was fired from over 8 klicks away and
has a nice ballistic arc with terminal guidance effects will do just fine.
Especially if it has a terminal boost phase with a ram jet that kicks it over
mach 3 onto your head.

Just how much energy do you think a 155mm round that is landing at mach 3 on
your top armor imparts? Can you say MDC 6?

Errr? In Stargrunt, jamming comms attempts is specifically mentioned as a use
for EW chits??

Maybe it's not allowed in DS2? It is, as Derk pointed out, specifically
allowed in SG2.

Assuming that you mean "the rules" or "the canon" when you write "the Cannon"
(cannon rarely assume very much, though their crews probably
do),
direction finding is part of the reason why DS2 doesn't use an elaborate

system for hidden movement and jamming is part of the reason why there are
communications rolls.

It's just that every platoon and its grandma is assumed to have EW assets, so
instead of treating each and every EW trooper explicitly in DS2 they're
subsumed into the basic game mechanics. Gives pretty much the same effect with
much less work <shrug>

Of course. And if you extrapolate today's laser detectors two centuries or so
into the future, the use of a "naked" laser beam (ie., not traveling
inside a shielded fiber line) for front-line communication might be
equal to a big "shoot here" sign. And so on...
