Description
This is the ability to use a heavy weapon, such as a trebuchet or a howitzer, for indirect fire – that is, to put fire onto a target area via a high ballistic arc or similar path.
For direct fire, use [[Gunner - Starfire]] skill. Roll against Artillery skill to bombard the
target.
Loaders can make Str-based Artillery rolls to improve the rate of fire of certain crew-served heavy weapons. See the appropriate weapon description for details.
You must specialize by weapon type. The available specialties vary by TL, but include one or more of:
Specializations
Beams
Any kind of heavy energy weapon that is fired from orbit, bounced off a mirror, or otherwise used against targets you cannot see.
Bombs
All kinds of unpowered, free-falling munitions.
Cannon
Any kind of heavy projectile weapon – bombard, howitzer, naval gun, etc.
Catapult
Any kind of indirect-fire mechanical siege engine, such as a trebuchet.
Guided Missile
Any kind of seeking or remotely piloted missile.
Torpedoes
Any kind of powered underwater projectile.
There is no default between specialties, some of which (e.g., Torpedoes) cover weapons that bear little or no resemblance to true artillery.
Artillery is a single skill only because all the weapons it covers use the same rules.
The weapons covered by each specialty will vary their tech familiarity based on the setting. For instance, Artillery (Cannon) would cover primitive bombards, brass cannon, breech-loading howitzers, and orbital railguns..
Familiarity is crucial here! Artillery (Cannon) covers both 81mm infantry mortars and 406mm naval guns, but going from one to the other will give -2 for weapon type (81mm vs. 406mm),
-2 for fire-control (visual spotting vs fire-direction center), and -2 for mount (bipod vs. naval turret), for a total of -6 to skill until you familiarize yourself with all the differences.
Note that the Forward Observation skill is generally required to designate targets for Artillery skill.
Modifiers
All relevant combat modifiers; -2 for an unfamiliar fire-control system (e.g., map coordinates when you’re used to satellite imagery) or mount (e.g., a naval turret when you’re used to emplaced guns), or for an unfamiliar weapon of a known type (e.g., 155mm when you are used to 203mm -4 or more for a weapon in bad repair.
