Btw. This stuff should be compatible with the d20 Modern rulebook, as opposed to the d20 WW2 thread stuff.

Ammunition & Cannons
A lot of different ammunition for cannons exists, and here are some of them:
HE (High Explosive): See Artillery rules.
AP (Armour Piercing Solid): Ignores 1 Hardness or Damage Reduction per 10mm bore.
APbc (Armour Piercing Burst Charge): As Armour Piercing Solid but adds 1 Fire Damage per 10mm bore.
AB (Air Burst): See Artillery rules, but explodes 5+1d6 squares above the ground.
Poison Gas: Instead of having an explosive charge, the shell is filled with poison gas.
Cannons:
AT (Anti Tank): Ignores 1 Hardness or Damage Reduction per 10mm bore (stacking with AP shells).
Fire-Linked Weapons (from d20 Modern SRD)
Fire-linked weapons are identical weapons that point and fire in the same direction. In effect, this arrangement creates a single weapon (fired with a single attack roll) that deals greater damage than either weapon alone.
Each full doubling of the number of fire-linked weapons (two weapons, four, eight, and so on) increases the damage by one-half the base damage and increases the DC against area attacks (autofire, flamethrowers, etc.) by 5. Fire-linking weapons adds +1 to the purchase DC of each weapon in the link.
Weapon Carriages
Weapons not already mounted in vehicles use the following stats:
Type: Vehicle, Size: 1 size category smaller than the gun, Hit Points: depending on the size of the gun and carriage (10 for Large carriages, 20 for Huge carriages, 40 for Gargantuan carriages), Occupants: 0, Cargo: 0, Hardness: 4, Speed: Drawn, Manoeuvre: -2 (stacking with the Handling of the vehicle attached to the carriage), Initiative -2 (stacking with the Handling of the vehicle attached to the carriage).
A Huge weapon (with carriage) weighs around between 200 lb. and 1.000 lb. A Gargantuan weapon weighs between 1.000 lb. and 60.000 lb. Colossal weapons weigh up to 26 tons (FlaK 128mm). These are guidelines to see whether a weapon can be towed or not. The internet is your friend in this case – look it up.
Note: If the carriage includes a front shield, the crewmembers gain 9/10 cover against attacks coming from the front. A shield improves the Hardness of the carriage by 4 (for Large carriages), 8 (for Huge carriages), or 12 (for Gargantuan carriages) against attacks from the front and increase the Hit Points by 50%.
Indirect Fire (from d20 Mecha SRD)
The weapon can fire shots in a high ballistic arc, like a grenade launcher, ballistic missile, or Howitzer. This lets the gunner shoot at targets hidden behind buildings, hills, or other obstacles (or shoot over the horizon, if the range is long enough).
If it is used to make an indirect fire shot, the attacker must be able to see the target, or someone else must spot it and radio or otherwise communicate its position to the attacker.
A weapon can fire indirectly at 10 times the usual number of increments (100 increments for most weapons). Note that the actual range increment is not increased: thus, Long Range fire will be rather inaccurate.
If the attack misses (see below), an observer can note where the attack hit and send a correction (or the attacker can correct by his or her self, if the target is in sight). Each correction gives a +2 bonus to hit, only to cancel any range increment penalties. It takes a full action for a distant observer to transmit a correction via communicator.
An artillery shell that misses still lands somewhere. Roll 1d8 scatter die, and for every Range Increment, the shell lands 1d6 squares away. For example, a target 6 Increments away will land 6d6 feet (30 to 180 feet away) away from the intended target.
Effects of Artillery (from Backstabbist’s 'shelling folks is fun')
Artillery are able to deal an incredible amount of damage, often against non-armoured units. The blast area depends on the size of the payload, and it can be summed up like this.
An artillery weapon roughly deals 1d8 damage per 10mm Bore.
Drop 1d8 for each square the target is from the point of impact.
A Reflex Save for half damage is DC 11 plus the number of dice of damage.
For example:
M1 75mm Pack Howitzer shell bursts with soldier “A” 15 feet away (three squares), soldier “B” 25 feet away (five squares) and soldier “C” 35 feet away (seven squares):
Soldier A: 7d8 (75mm) -3d8 (3 squares) = 4d8, Ref DC (11+ 4) = DC 15
Soldier B: 7d8 (75mm) -5d8 (5 squares) = 2d8, Ref DC (11+ 2) = DC 13
Soldier C: 7d8 (75mm) -7d8 (7 squares) = no damage
So the blast radius for a M1 75mm Pack Howitzer is 35 feet, or 7 squares.
Now, let us have a look at a 155mm M1 “Long Tom” Field Artillery blast instead:
GuyA: 15d8 (155mm) -3d8 (3 squares) = 12d8, RefDC (11+ 12) = DC 23
GuyB: 15d8 (155mm) - 5d8 (5 squares) = 10d8, RefDC (11+ 10) = DC 21
GuyC: 15d8 (155mm) -12d8 (12 squares) = 3d8, RefDC (11+ 3) = DC 14
Any creature affected by artillery is shaken and deafened for a number of rounds equal to the number of damage dice dealt. Additionally, a creature must make a Fortitude Save with a DC equal to the Reflex Save DC (see above) to avoid further ill effects. If a creature fails its save by 5 or more, he/she is nauseated. If a creature fails its save by 10 or more, he/she is stunned. If a creature fails its save by 15 or more, he/she is cowering. All these effects stack and last for a number of rounds equal to the number of damage dice dealt. After each condition shift, the duration is halved (round up). For example, GuyA from the 155mm example above survived the attack but failed his Fortitude against the ill effects by 16 (rolling 7). He then is cowering, shaken and deaf for 12 rounds, stunned for 6 rounds and finally nauseated for 3 rounds.
Shaken
A shaken creature takes a –2 penalty on attack rolls, saving throws, and skill checks.
Deafened
The creature can’t hear and takes a –4 penalty on initiative checks. The character can’t make Listen checks.
Nauseated
Creatures who are nauseated are unable to attack or do anything else requiring attention or concentration. The only action such a character can take is a single move action per turn.
Stunned
A creature who becomes stunned loses his or her Dexterity bonus, drops what he or she is holding, and can take no attack or move actions. In addition, the character takes a –2 penalty to Defence.
Cowering
The creature is frozen in shock, loses his or her Dexterity bonus, and can take no actions. In addition, the character takes a –2 penalty to his or her Defence.
What'ya think?
Edit: Changed from 5 squares to 1d6 squares per RI.
Edit2: Added a +5DC to Fire-Linked weapon's area of effect saves.
I like where you went with my shelling plan.
<...>
An artillery shell that misses still lands somewhere. Roll 1d8 scatter die, and for every Range Increment, the shell lands 5 squares away. For example, a target 6 Increments away will land 150 feet (30 squares) away from the intended target
I'm not sure I like the Indirect scatter system d20Mecha gave. Actually, the mechanic looks good, I just think at 10RI a 300'RI howitzer shouldnt mandate to 250'miss @ 1000m. I would suggest making it 1d6 squares per RI rather than a fixed 5 squares in the d8 scatter direction (or d360 if you are a detail freak ;))
Great stuff!
Thanks Cl.Bragg! :D Feedback appreciated.
Outstanding!

Thank you. I hoped you'd like it.

Hehe. :D Actually, I added that coz I wanted arty to land somewhere. It was slightly rushed. I made it 5 squares so we didn't have to roll that many dice. ;) I've changed it though. I like artillery to be rather random, so 1d6 seems good.
Edit: Btw. I was really frustrated with the 75mm vs. 76,2mm vs. 17-pdr, so I ended up giving the QF 17 Pounder a mastercrafted +1 damage. I think it's a pathetic solution, but a solution nonetheless.
Edit2: I can't seem to find CyberDave's System. Do you have a link to it?
Thanks
