{{:Spearhead 1944 Field Manual}}
=== Overview ===
The Indirect Fire Support system provides battlefield support in various forms: mortars, artillery, CAS, and even direct support from nearby tanks.


= Mission Variables =
The support occurs both by player call-in requests, as well as automatically, and is based on the available intel of enemy threats and capabilities in any given moment.
{{Feature|warning|Changing these variables can break the IFS feature!}}
=== Usage ===
When activated via module or functions, the system operates the autonomous form of fire support in the background, depending on indirect fire support assets present in the scenario and mission setup without any action required from the player. That said, by spotting enemy units and vehicles, players, as well as friendly AI forces, will effectively provide information about possible targets to the allied supporting assets, which may affect their decision-making and behavior.


{| class="wikitable sortable style= "width=100%";"
The called-in form of indirect fire support is under the player's direct control. What operations are available and any limits to the activities depend on the mission-specific setup. By using the action menu and hold actions, players can call in mortar, artillery, or CAS support or ask nearby allied tanks for direct fire support. Players can also send a request for emergency fire support that's provided by any available asset at a given moment.
|-
=== Detailed information ===
! Variable Name !! Data Type !! Default Value !! Locality !! Description
Autonomous fire support for all sides is based on the presence of the artillery assets in the scenario and CAS presence defined in the mission setup. Amongst known enemy units and vehicles, the most tempting targets are chosen when an allied unit is at the appropriate distance to serve as the forward operator (FO). Potential targets must also meet a few additional requirements - including low enough risk for friendly fire.
|-
 
| {{hl|SPE_IFS_pairingtriesperbattery}} || [[Scalar]] || <sqf>5</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
When the target is accepted, the allocated artillery asset will start the aim procedure, which takes around 20 seconds, in order to take into account the target's movement vector with the assumption that it will continue to move.
|-
 
| {{hl|SPE_IFS_targetblacklist}} || [[Array]] || <sqf>[]</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
Autonomous artillery barrage is a subject of both general aim error and individual round spread. Depending on the mission setup, usually, the main firing action is preceded by a single spotting round - and in the case of players under threat, a few notifications about the incoming fire.
|-
 
| {{hl|SPE_IFS_progresscallwheninvalid}} || [[Boolean]] || <sqf>true</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
Meanwhile the called-in artillery support is fired at the location requested by the original caller. However, each round is still subjected to a statistical spread, leading to certain inaccuracy.
|-
 
| {{hl|SPE_IFS_planes_ind}} || [[Array]] || <sqf>["SPE_P47", 1]</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
Via mission setup, certain areas or objects may be blacklisted. As a result, calling fire support to strike those will be impossible. The same applies to the immediate vicinity of the caller.
|-
 
| {{hl|SPE_IFS_allprojectiles_ger}} || [[Array]] || <sqf>["", "spe_sc250_timed_short_bomb", "spe_sc250_timed_short_bomb_submunition", "spe_sc50_timed_short_bomb", "spe_sc50_timed_short_bomb_submunition", "spe_s_105l28_gr38", "spe_b_20x82_he", "spe_b_13x64_hei", "spe_sh_81_he", "spe_sh_fa_mle_1932_he"]</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
CAS fire support, both autonomous and called-in, works in a similar way. Typically, though, it's much more precise against moving vehicles since the pilot can correct his aim till the last moment.
|-
 
| {{hl|SPE_IFS_emergencycallbaseinterval}} || [[Array]] || <sqf>[[30, 45, 60, 90, 45], [30, 45, 60, 90, 45], [30, 45, 60, 90, 45], [30, 45, 60, 90, 45]]</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
Emergency support calls are meant as a desperate last resort. The first available support provider of any type will automatically pick a hostile target near the caller that seems the most threatening, without any friendly fire avoidance - so beware. It's also possible there will be no available support at all.
|-
 
| {{hl|SPE_IFS_calledsupportproviders}} || [[Array]] || <sqf>[[[], [], []], [[], [], []], [[], [], []], [[], [], []]]</sqf> || style="text-align:center;" | {{Icon|globalEffect}} || TBD
In general, depending on mission setup and game difficulty, called-in fire support will have various usage conditions and limitations, including radio availability, amount of calls, time interval between the calls, or inability to call the same type of support many times simultaneously. The current status of support availability, if any is present at all, is shown directly in the action menu.
|-
 
| {{hl|SPE_IFS_rdtable}} || [[Array]] || <sqf>
Finally, if the player is close enough to an allied tank, it may be possible to point the tank gunner to a target and engage via the action menu.
=== Configuration ===
Mission parameters may allow customization of certain elements of the system for the given play-session in multiplayer mode.
=== Mission maker setup and use ===
The advanced customization of IFS is possible via the module to a large extent and even more so via scripting
 
Detailed documentation is found on the [[Spearhead 1944]].
=== Indirect Fire Support ===
During the game, you may encounter or cause various indirect fire support events.<br/><br/>Soldiers present on the battlefield, AI and players alike, will automatically report spotted hostile targets to HQ. HQ, according to its own judgment, may issue orders to attack a worthy target with its own artillery or aerial asset if present and not busy elsewhere.<br/><br/>Sometimes, players also have the possibility to call in such support directly.
{{Feature|informative|When caught by an incoming artillery barrage, your best friends are - hardcover, keeping your head down, and distance.}}
=== Called-in Fire Support ===
Select and hold a support action to call in the chosen type of support to a position or target in the middle of the screen.<br/><br/>Avoid requesting support too close to your own or allied positions - ordnance has a considerable blast radius and spread.
{{Feature|informative|Red aiming helpers visible on the screen while holding an action can also be displayed via the {{hl|"T"}} key.}}

Overview

The Indirect Fire Support system provides battlefield support in various forms: mortars, artillery, CAS, and even direct support from nearby tanks.

The support occurs both by player call-in requests, as well as automatically, and is based on the available intel of enemy threats and capabilities in any given moment.

Usage

When activated via module or functions, the system operates the autonomous form of fire support in the background, depending on indirect fire support assets present in the scenario and mission setup without any action required from the player. That said, by spotting enemy units and vehicles, players, as well as friendly AI forces, will effectively provide information about possible targets to the allied supporting assets, which may affect their decision-making and behavior.

The called-in form of indirect fire support is under the player's direct control. What operations are available and any limits to the activities depend on the mission-specific setup. By using the action menu and hold actions, players can call in mortar, artillery, or CAS support or ask nearby allied tanks for direct fire support. Players can also send a request for emergency fire support that's provided by any available asset at a given moment.

Detailed information

Autonomous fire support for all sides is based on the presence of the artillery assets in the scenario and CAS presence defined in the mission setup. Amongst known enemy units and vehicles, the most tempting targets are chosen when an allied unit is at the appropriate distance to serve as the forward operator (FO). Potential targets must also meet a few additional requirements - including low enough risk for friendly fire.

When the target is accepted, the allocated artillery asset will start the aim procedure, which takes around 20 seconds, in order to take into account the target's movement vector with the assumption that it will continue to move.

Autonomous artillery barrage is a subject of both general aim error and individual round spread. Depending on the mission setup, usually, the main firing action is preceded by a single spotting round - and in the case of players under threat, a few notifications about the incoming fire.

Meanwhile the called-in artillery support is fired at the location requested by the original caller. However, each round is still subjected to a statistical spread, leading to certain inaccuracy.

Via mission setup, certain areas or objects may be blacklisted. As a result, calling fire support to strike those will be impossible. The same applies to the immediate vicinity of the caller.

CAS fire support, both autonomous and called-in, works in a similar way. Typically, though, it's much more precise against moving vehicles since the pilot can correct his aim till the last moment.

Emergency support calls are meant as a desperate last resort. The first available support provider of any type will automatically pick a hostile target near the caller that seems the most threatening, without any friendly fire avoidance - so beware. It's also possible there will be no available support at all.

In general, depending on mission setup and game difficulty, called-in fire support will have various usage conditions and limitations, including radio availability, amount of calls, time interval between the calls, or inability to call the same type of support many times simultaneously. The current status of support availability, if any is present at all, is shown directly in the action menu.

Finally, if the player is close enough to an allied tank, it may be possible to point the tank gunner to a target and engage via the action menu.

Configuration

Mission parameters may allow customization of certain elements of the system for the given play-session in multiplayer mode.

Mission maker setup and use

The advanced customization of IFS is possible via the module to a large extent and even more so via scripting

Detailed documentation is found on the Spearhead 1944.

Indirect Fire Support

During the game, you may encounter or cause various indirect fire support events.

Soldiers present on the battlefield, AI and players alike, will automatically report spotted hostile targets to HQ. HQ, according to its own judgment, may issue orders to attack a worthy target with its own artillery or aerial asset if present and not busy elsewhere.

Sometimes, players also have the possibility to call in such support directly.

ⓘ
When caught by an incoming artillery barrage, your best friends are - hardcover, keeping your head down, and distance.

Called-in Fire Support

Select and hold a support action to call in the chosen type of support to a position or target in the middle of the screen.

Avoid requesting support too close to your own or allied positions - ordnance has a considerable blast radius and spread.

ⓘ
Red aiming helpers visible on the screen while holding an action can also be displayed via the "T" key.

MissionNamespace Variables

IFS

SPE_IFS_2PhWithoutFO

Data Type: Boolean

Locality: GEGlobal

Default Value:false

Description: If SPE_IFS_FO is not empty, arty fire mission is divided into two phases. First phase is less accurate and less numerous (probing fire). If this variable is true, two-phase fire is used also without a "proper" FO from SPE_IFS_FO array

SPE_IFS_aacapableassets

Data Type: Array

Locality: GEGlobal

Default Value:["spe_flak_30","spe_flak_38","spe_us_m16_halftrack","spe_m45_quadmount"]

Description: Assets that are capable of AA.

SPE_IFS_acc

Data Type: Number

Locality: GEGlobal

Default Value:2

Description: General accuracy multiplier. Aiming error is multiplied by this value. Set to 0 for spot-on salvo aim (but individual round spread still is present).

SPE_IFS_acceptedRadioBackpacks

Data Type: Array

Locality: GEGlobal

Default Value:["b_spe_ger_radio","b_spe_us_radio","b_spe_us_radio_alt","b_spe_us_radio_packboard","b_spe_us_radio_packboard_light"]

Description: Backpacks considered as proper radio backpack for requested support calls requirement (all lower case!).

SPE_IFS_active

Data Type: Boolean

Locality: GEGlobal

Default Value:true

Description: If false, IFS main loop will exit permanently.



SPE_IFS_AIBombHelper_disable

Data Type: Boolean

Locality: GEGlobal

Default Value:true

Description: In the performance-friendly CAS mode, if false, Ai Bomb Helper will be responsible for guiding CAS bombs on target. If true - bombs will be guided by different code, which guides rockets and MG bullets. In the each frame CAS mode, bombs are not guided.

SPE_IFS_allowAdvancedHints

Data Type: Boolean

Locality: GEGlobal

Default Value:true

Description: Should IFS-specific advanced hints be displayed (switch false, when not, switch true, when allowed).

SPE_IFS_allowMortarsAgainstTanks

Data Type: Boolean

Locality: GEGlobal

Default Value:false

Description: Should mortars be considered to fire at tanks.

SPE_IFS_amount

Data Type: Number

Locality: GEGlobal

Default Value:6

Description: Default number of shells per arty fire mission.

SPE_IFS_amountMultiplier

Data Type: Array

Locality: GEGlobal

Default Value:[[1,1,1],[0.33,0.5,1]]

Description: Shells per arty fire mission amount multiplier [mortars,heavy arty] (final amount is rounded up) each for [infantry,soft,tank-or-artillery] targets.

SPE_IFS_areaBlacklist

Data Type: Array

Locality: GEGlobal

Default Value:[]

Description: No target within included areas will become a target of IFS. Also IFS will try to avoid any shells dropping inside those areas. No 100% warranty. Accepted are all entries handled by inArea command (trigger, marker, location or [center, a, b, angle, isRectangle, c] array). If object is given as a center, area will be each check updated depending on object's position.

Description: Each entry in the array is a condition. If one of these conditions returns true, the player has access to IFS. Inside each condition the special variable _unit is available.

Conditions:

  1. Checks if the player is set to be a transmitter via scripting.
  2. Checks if the player's vehicle is set to be a transmitter via scripting.
  3. Checks if the player is group leader.
  4. Checks if the player has a whitelisted radio backpack.
  5. Checks if the player has a radio item.
  6. Checks if the player is in a tank. Tanks always have radios.
  7. Checks if one of the units that is in the same vehicle as the player either is a transmitter, has a radio backpack or has a radio item.
  8. Checks if a friendly vehicle (not civilian) is in reach of the unit. Distance is based on difficulty.
  9. Checks if a nearby friendly unit or vehicle (not civilian) can be used to relay a message. Distance is based on difficulty.

Modification:

SPE_IFS_artyAvailability_specific can be modified to suit your needs. Just remove all entries that are not wanted, or add custom conditions to it. For performance reasons it's recommended to put less performance intense condition at the front of the array and vise versa.
