These are the Parameters for Artillery Missions. Which Parameters are shown for a specific request depends on the chosen support asset (for example, Smoke Missions are only available for assets that actually have smoke ammunition available):

Sets the size and shape of the area to hit:
Point Fire - focuses on a single Action Spot or specific enemy unit
Area - one click for the center and one for the perimeter Line - requires two clicks, one for each end of the line
Number - sets the portion of the Asset to use, from 1 to the total number in Asset (usually 2, 3, or 4)

Responsible for establishing initial Rate of Fire (ROF) and sustained ROF:
Emergency - no spotting rounds, otherwise like Heavy (not available for pre-planned artillery strikes)
Harass - very slow ROF to conserve ammunition
Light - slow ROF, remaining at slow ROF
Medium - medium ROF, then going to sustained ROF
Heavy - max ROF, then going to heavy sustained ROF
Precision - single round, fires up to one precision-guided shell per tube at the target. Only available
for Point Fire targets. No spotting rounds and Adjust is not available.
Smoke - medium ROF, firing smoke ammunition to create a smokescreen rather than explosive ammo to damage or destroy the target

Determines number of rounds to use per mission:
Quick - 2-4 rounds
Short - 6-12 rounds
Medium - 12-18 rounds
Long - 20-28 rounds
Maximum - exhausts ammo supply
Type- sets the munition mix based on the target type:
General - generic setting
Personnel - weights in favor of airburst antipersonnel rounds.
Note: Planned artillery strikes as well as strikes or- dered on a TRP can airburst if set to a “personnel” target. This simulates the use of timed fuses. Not all shells will airburst, although airburst capability is much more common in modern war titles
Delay - establishes when to start the support, prep time inclusive. The options are:
Immediate - no extra delay
5 Min - sets for 5 minutes min
10 Min - sets for 10 minutes min
15 Min - sets for 15 minutes min

These are the Parameters for Air Missions (which Parameters are actually shown depends on the selected Air asset):
Sets the size and shape of the area to hit:
Point - focuses on a single Action Spot or unit
Area - one-click for the center and another click for perimeter

Responsible for establishing the scope of the attack:
Light - lighter Munitions
Medium - mix of lighter and medium Munitions
Heavy - medium Munitions with a smattering of lighter

Sets the munition mix based on the target type:
General - favors unguided HE munitions
Personnel - favors HE munitions

Establishes when to start the support, prep time inclusive. The options are:
None - no extra delay
5 Min - sets for 5 minutes min 10 Min - sets for 10 minutes min ect.
