WEAPON TYPES.
I think the weapon terminology in the BBB is more or less ok as is.
But I would like to suggest the following additions.
Small arms fire should be inffective vs vehicles.No +D6 for pen rolls!
All other weapons get the +D6 vs vehicles ,assault,heavy and ordnance.
Specific anti vehicle weapons (that get an extra D6 vs vehicles ,now just double the result of the D6 rolled.Melta, fusion weapons and MCs etc?.)
Optional rules for high rate of fire assault and heavy weapons.(3 shots or more.)
Concentrate fire vs vehicles.
As heavy machine gun /AA cannon derivitives,generaly fire bursts of shots over a wide area, to be effective vs fast moving 'dodging' infantry, as vehicles cannot dive prone rtc the weapons could concentrate fire on a particular spot on a large taget,(Vehicle/MCs.)
The player may elect to fire at one spot on the target vehicle.
If the player choses to do this ,the weapon fires one shot(concentrated burst) which adds the ROF to the D6 roll for armour pen ,rather than just D6.
EG Heavy Bolter.
Rng 36/str 5/heavy 3.
Using CF rules ,bcomes,Rng 36/str (5 +3)=8 Heavy 1.
Assaultcannon .
Rng 24/str 6Heavy 4.
using CF rules,becomes,Rng 24/str (6+4)=10 heavy 1.
(Possibly what the GW devs were trying to achive with the assaultcannon 'rending 'rules ,but forgot the burst of fire have to hit the same spot on the target vehicle to 'jackhammer ',through the armour,and so should reduce the number of shots?)
VEHICLE DAMMAGE CHART.
Modified strenght......Result.
-1..........crew shaken on D6 roll of 5+
0 to 1 .....crew shaken.(2 or more of this result per turn ,upgraded to crew stunned result)
2 to 3 .....crew stunned.
4 to 5.......weapon destroyed.(If no weapons left upgrade this result to motor dammaged.)
6 ............motor dammaged (reduce movment by 1/3 per motor dammaged result)
7+...........vehicle explodes.
Notes..
If a vehicle sustains 3 motor dammaged results (possibly 2 for skimmers?) the vehicle is destroyed.
So vehicle structure points culd be represented by the number of hits required to immobilise the vehicle.As a value after the movment value?
Eg landspeeder,Movement value,(M)12/2.So the first M hit halves the movment.second M hit destroys the land speeder.
Lemanruss, Movment value,(M),6/3. So the leman russ has its movment reduced by 2(1/3of starting movment value) for the first Mobility hit,
reduced by 4, for the second Mobility hit.(2/3 of original movment value.)
And destroyed om the 3rd mobility hit.
I am working on the concept that a vehicle crew will bail out, if they turn unto sitting ducks for all th anti vehicle weapons to take pot shots at!!.
Ordnance and close combat hits add +1 to the modified strenght result.
TO HIT MODS.
Firing at targets at a range of 18 inches or more.-1
Firing at targets in light cover-1
Firing at units on charge orders-1.(As action description.)
Firing at targets in heavy cover-2
Firing at large targets ,(vehicles and MCs+1.)
Firing through other non vehicle units,-1?
MORAL.
Units not exempt from moral checks,must check moral when...
The unit looses an assault ,as current rules for LD mods.(Number of casualties ,out numbering etc.)
The unit falls below 75% of starting unit strenght.(The unit must test every turn if below 50% of starting unit strenght.)
Freindly unit within 6 inches is destroyed of Falling Back.
A freindly HQ unit within 12 inches is destroyed or Falling Back.
Out gunned ,the unit recieves twice as many potentialy dammaging hits ,as the unit strenght of the unit.(Within 2 enemy actions?).
(Only count hits that can dammage the unit.)
Modified LD...Result
8+..OK unit act normaly.
7....Shaken
6....Stunned
5 or less,Fall back.
