Some SG2 ideas

Vehicle Defensive Systems (SG2):
----------------------------------

Point Defence Charges (PDC):
Represents claymore-like mines that are triggered by an incoming
missile
and hurl framents out to destroy the incoming missile.
They are attached to the outer hull of the vehicle.
When PDC-grid is active, give the vehicle an extra d6 in defence when
engaged by GMS or IAVRs. This is a "charged item".
Each time a vehicle with PDC grid is hit, if the hit is
non-penetrating,
a roll of 3 is considered to remove one PDC charge.
Activating a PDC grid is 1 action, as is deactivating.
The PDC grid is ineffective against GMS/H or larger missiles. It is
effective against GMS/P and GMS/L.
PDC sensors may be jammed with EW.

Anti Infantry Defence Charges (AIDC):
Represents claymore-like mines that are triggered proximity of an
infantry unit to the vehicle.
They are attached to the outer hull of the vehicle.
When AIDC-grid is active, any enemy infantry unit that
comes within the perimeter range (set at activation) is attacked
with a CDM. When passing any friendly infantry unit, roll vehicle
sensor quality (basic, enh, superior) + unit quality. If a double 1 is
rolled,
the AIDC system has been miscalibrated and goes off. This is a
"charged item".
Each time a vehicle with AIDC grid is hit, if the hit is
non-penetrating,
a roll of 4 is considered to remove one AIDC charge.
Activating a AIDC grid is 1 action, as is deactivating.
This action includes setting perimeter range (from 1"-5").
AIDC sensors may be jammed with EW.

Reactive armour:
Works against various shaped charge warheads to stop the anti-armour
jet from forming.
Effective against conventional guns, IAVRs, and GMS of various sizes.
If the vehicle is fitted with reactive armour (a charged item), denote
it by
applying an R after the armour level (5R). In the event of an attack
by an appropriate type of weapon,
the reactive armour may stop the warhead from being effective. Once a
hit has been determined,
before determining armour penetration, roll d6. On a 1-4, the Reactive
armour has stopped the
weapon from working effectively. Roll 1/2 (round down) the dice for
the attack on the armour.
For example, a GMS/L hits reactive armour, a 2 is rolled on the D6.
Consequently it only rolls 1d12
against the armour rather than the normal d12x2. Note, with GMS/P,
this will totally nullify the
weapon if the reactive armour roll is successful.
Each time the vehicle is hit by a kinetic projectile attack (even
small arms) that produces a
non-penetrating hit, on a roll of 5 a reactive armour charge is
wasted.

Point Defence Fire Control (PDFC):
Represents a sensor grid that tracks rapid fire weapons onto
incoming weapons. It is a 1 space for every weapon system it is slaved
to. It may be hooked to SAWs (mimimum FP d10), RFAC/1, GAC/1 or HEL/1.
Activating PDFC and linking it to weapons takes 1 action, as does
deactivating. A weapon under PDFC control must be de-linked to be used
for offensive fire. If the weapon is in-arc, then it can be used to
defend the vehicle from any incoming GMS or IAVR.
When a PDFC is activated, give the defending vehicle an extra die
based on the system quality (basic, enhanced, superior).
Note PDFC can be jammed by EW. If it is jammed, the defender does not
get the extra dice vs the incoming fire.
PDFC will work against GMS/P, GMS/L, GMS/H but not anything larger.
If PDS is forced to engage more than once per round due to a large
volume of incoming fire, each time the system quality is considered
one level lower (overwhelming effect) to a minimum of D4.

Anti Armour Rifle Grenades (RG-AA)
Fired from a GL (underbarrell) - may fire one per fire action if with
squad fire, or one separately as support  weapon. Impact D8*.
Typically a squad carries anywhere from one shot to one shot per man.
If fired at a bunker,  treat as a point fire vs. a dispersed target.
If fired alone, roll D4 for FP + Quality.

Infantry Smoke Grenades (RG-HC)
Fired from a GL (underbarrell) - may fire one as an action. Typically
a squad carries anywhere from one shot to one  shot per man. FP
effective d4. Roll D4+Quality against a range dice. If either dice
beats the range dice, grenade  lands where it was aimed. Place a 2"
diameter smoke screen centred on the impact point. It can be coloured.
This can  be used as an aiming point for Arty or TacAir. It blocks
LoS. If both dice are beaten by the range die, then the round
deviates by the difference between the range die and the nearest firer
die, random direction.
