Well this is my interpretation of point defense rules which like quite a
few other things seem to have been left out of MT even though they decide
to leave meaningless charts of neat things with no explanations. Could
it be that s-one from 'Judges Guild '
arrggg editors.
actually is sabotaging GDW :-)
First of all point defense targetting modules are standard only on ship
type hardpoints. Those that take 13.5+ kl etc. So I think it is misleading
to assume PA-11 is mounted hardpoint. As it is considered a gun and not
a hardpoint.
In 'vehicle' design you have to specify which weapon the PDF module is
to be used for. Multiple weapons require multiple modules.
Anyway here's the scoop on PDF. This is from 'Striker' but apparently
seems valid for MT as most Striker stuff does.
A weapon with Point Defense Fire(PDF) module can do 3 separate missions.
1. Normal fire. Uses normal fire rules but ignores enemy movement DMs due
to its superior fire control. Nasty against those high speed Zho ground
speeders.
2. Overwatch. Weapon may engage any indirect fire rounds.
3. Dedicated support. PDF locks on to specific person or vehicle and tries
to follow its movement. Any missiles, rockets and indirect fire against
supported unit within 100m of it may be engaged by PDF unit.
These missions are mutually exclusive. For overwatch and dedicated support
all non-grav vehicles must be stationary due to the high accuracy required.
Against Direct Fire:
Unit must see last 150m of weapons trajectory. Unit rolls as per normal fire
No movement DMs. Any hit destroys one round. If multiple hits, owner may
(of PDF) chooses which rounds to take out. So if u have 4 missiles inbound
and you hit 3 times, u pick which three.
Against Indirect Fire:
You roll the following number of dice to hit inbound artillery fire based
on TL of PDF module:
TL-9:4
TL-10:6
TL-11:8
TL-12:10
TL-13:12
TL-14:14
TL-15:16
This is the number of artillery rounds destroyed.
>From each die subtract PDF TL-Art round TL. E.g TL-10 rolls 6 die against
artillery fire. 4 are dedicated to a TL-15 artillery barrage and 2 are
assigned to a TL-10 barrage. There is no modifier to TL-10 barrage but there
is a -5 to EACH die fired against TL-15 barrage.
As MRL's overload defenses by firing within a short period of time(what about
rapid fire M-D guns??Hmm) divide the numbers of rounds destroyed by 2.
This leads us to the other question. How the hell do u use artillery?
If anyone is interested I'll post it. Otherwise I hope this clears up most of
the mess. Most units don't have to worry about indirect fire anyway.
That Gram grav-tank is real nasty with its PA on direct fire. Makes mince
meat of a few Imp 'Trepida's(what a wimpy name for a tank!)
