A3 Locking Review

New tech

New means with TKOH (Hinds) and A3. Or new since A2/OA.


lockSeekRadius = float;

Specifies the maximum distance from the position at which it was shot, in which the automatic search for suitable targets.

autoSeekTarget = bool;

Disable automatic search goals. If set to false, the missile guides only for location / destination that was specified at the time of the shot.

lockType = [0,1,2];

For guided missiles

  • 0 = fireAndForgetLT (current system)
  • 1 = keepLockedLT (not yet done)
  • 2 = manualLT (manualy guided)
airLock = [0,1,2];

Can target flying objects.

  • 0 = lockGroundTT (air lock disabled)
  • 1 = lockAirGroundTT (air and ground lock)
  • 2 = lockAirTT (air only lock (NEW))

Requires irLock = 1; to work. Also makes AI to track air units with the given the ammo (weapon). This may not be desirable for non heavy MG weapons as it the AI gunner to focus on air targets - first while ground targets are ignored meanwhile even though the ground target may actually be the bigger threat.


Nothing new so far.


allowTabLock = bool;

Vehicle turret setting. Determines if TAB lock is enabled.

showAllTargets = [0,1,2];

Vehicle turret setting. Displays/marks all known lockable targets in the HUD as rectangles.

  • 0 = showAllNo (current system)
  • 1 = showAllCadet (show extended if HUD is enabled)
  • 2 = showAllYes (always show)

Existing tech


irLock = bool;

Can lock vehicle with irTarget=1/true.

laserLock = bool;

Can lock onto LaserTarget object (which are created using laser Designator - both by infantry or vehicles).

nvLock = bool;

Can lock onto NVTarget object (ie NVG marker that infantry can throw a grenade).

artilleryLock = bool;

Can lock onto ArtilleryTarget object (creates the Fire command).

manualControl = bool;

Missile follows the cursor, if not locked onto a target (canLock = 1/2). maxControlRange, maneuvrability and missile speed are very important for manual control. AI is able to guide missiles manually too.

maxControlRange = float;

How far one can manually control the missile - during maxControlRange <10 unguided rockets are all

maneuvrability = float;

Defines how much the missile is able to turn / how well it can be controlled during the flight.

trackLead = [0,1];

​​Range 0-1, how much is the missile performing "smart" tracking, which assumes onboard computer computing predicted target position at the impact time, resulting in a mostly straight flight trajectory.

  • 1 = Means this computation result is used 100%
  • 0 = Means it is not used at all
trackOversteer = float;

Simulates the analogue controls used in missiles, where it reacts directly to the target's relative position by adjusting its flight direction.

  • 1 = no oversteer / Means the missile always tries to direct itself directly at the target.
  • 0 = ???
sideAirFriction = float;

Indirectly affects missiles turning / the flight path once the missile changes its orientation. The higher the side friction the more accurate is the maneuvring with the missile.


ballisticsComputer = [0,1,2];

Weapon attempts to calculate and shift the aimpoint to hit a locked target based on range, target movement, own movement, and ballistics of selected ammo type.

  • 0 = disabled
  • 1 = Arma2 TAB lock results in zeroed scope, Arrowhead: added also manual zeroing (PgUp/PgDwn)
  • 2 = Arrowhead: only manual zeroing (PgUp/PgDwn)
canLock = [0,1,2];

Determines if the weapon can lock onto targets.

  • 0 = can not lock
  • 1 = can be targeted at a lower/cadett difficulty (Recruit + Regular)
  • 2 = can always lock
lockAcquire = bool;

Determines if rocket launcher locks automatically a target or player has to use RMB.

  • 0 = automaticLA (current rocket launcher system)
  • 1 = manually (use RMB)
weaponLockDelay = float;

Determines in seconds how long it takes before the gun reaches LOCKED after marking targets with TAB/RMB.

weaponLockSystem = [0-15];

Set the weapon's locking technology - determines which signature a CM system can notice. Can be multiple at the same time.

  • 0 = None
  • 1 = CM_Lock_Visual
  • 2 = CM_Lock_IR
  • 4 = CM_Lock_Laser
  • 8 = CM_Lock_Radar
cmImmunity = [0-1];

Determines the probability of not getting distracting by a CM. Flares and chaffs are dropped in pairs, while smokes are single.

  • CMImmunity_GOOD = 0.8 (for pair of flares its 0.64, for four 0.4)
  • CMImmunity_MIDDLE = 0.65 (for pair of flares its 0.4, for four 0.16)
  • CMImmunity_BAD = 0.5 (for pair of flares its 0.25 , for four 0.06)


radarType = [0,1,2,4];
  • 0 = none
  • 1 = tactical display
  • 2 = vehicle radar
  • 4 = air radar
lockDetectionSystem = [0-15];

Determines which weapon's lock type the vehicle can detect.

  • 0 = None
  • 1 = CM_Lock_Visual
  • 2 = CM_Lock_IR
  • 4 = CM_Lock_Laser
  • 8 = CM_Lock_Radar
incomingMissileDetectionSystem = [0,16];

Determines what type of incoming missile can be detected (and shown on the radar?).

  • 0 = None
  • 16 = CM_Missile
xxxCanSee = [0-65];


  • 1 = CanSeeRadar
  • 2 = CanSeeEye
  • 4 = CanSeeOptics
  • 8 = CanSeeEar
  • 16 = CanSeeCompass
  • 1+16 = CanSeeRadarC
  • 31 = CanSeeAll
  • 32 = CanSeePeripheral
irScanToEyeFactor = float;
irScanRangeMin = float;
irScanRangeMax = float;

Those settings can be used instead of irScanRange to make IR scan dange depend on the visibility distance. If there is irScanRange, fixed value is used. The same thing can also be acomplished by setting both irScanRangeMin and irScanRangeMax to the same value.

If there is no irScanRange, IR scan range is calculated as:

scanRange = visibility_range * irScanToEyeFactor;
if (scanRange<irScanRangeMin) scanRange = irScanRangeMin;
if (scanRange>irScanRangeMax) scanRange = irScanRangeMax;

Where visiblity_range is basically a drawing distance, but may be shortenet by rain or fog.

irScanGround = bool;



Config only work

Simulate laser guidance by helicopter weapons (like Hellfire for AH-64 Apache and AH-1Z Cobra)

URL: [13]

HowTo: Set canLock=1 and manualControl=1 or add Laserdesignator_mounted and irLock=0 (or Make laserLock and nvLock independant to canLock).

See also: Cannot acquire laser target for BAF Wildcat CRV-7 PG rockets if "Auto guide AT" is turned off in difficulty

Beeping noise when acquiring missile lock is WAY too loud

URL: [18]

HowTo: Add Laserdesignator_mounted weapon to more vehicles.

Require engine changes

Ordered by assumed priority (first is highest) and hopefully limited effort.

Add option to restrict radar locking (TAB target cycling) of vehicles

URL: [19]

Comment: Could be done with canLock=1 for all non Fire-And-Forget (FNF) guided missiles as AutoGuideAT makes it a difficulty setting.

Add difficulty option to disable radar of vehicles (that don't have one in reality)

URL: [20]

Comment: Needs a new config value like hasRadar, link it to difficulty level or a new setting and disable it for vehicles with hasRadar=1 in Veteran/Expert. This way new players could still play with "always radar" in lower difficulty.

Add option to disable friend-foe radar signature (difficulty setting)

URL: [21]

Comment: To keep it for lower difficulty, but allow more realistic and better gameplay in Veteran Expert. Could be linked closely with the suggested IFF changes.

Add difficulty option to hide the locking cursor

URL: [22]

Comment: To make player rely on locking sound only. Defined in CfgInGameUI-Cursor/lock/target/select_target.

Radar targets and locking ability needs to be limited by object drawing distance for units/vehicles with irScanToEyeFactor=1

URL: [23]

Comment: To reduce/remove locking abuse. Only with irScanToEyeFactor>1, radar detection/locking should go beyond viewable distance.

Airborne chopper to be rendered in larger distances

URL: [24]

Comment: Ondrej: The rationale why only planes and not helis that planes are mostly flying higher, and there are less planes in the mission, but in principle the solution can be easily extended for helis as well later.

Improve radar and friend-foe-identification (IFF) simulation

URL: [25]

Comment: Picks up ideas from Hladas in the BI forum discussion. Improvements here would help big time.

irScanGround = 0/false does not limit radar/target identification to air vehicles

URL: [26]

Comment: Seems like a bug or functionality is different. No (for me accessible) information available about it.

Simulation shotRocket ignores ballistic profile (gravity) after rocket burn out

URL: [27]

Comment: Makes rockets way too easy to shoot distant targets. Not realistic and looks weird too.

Disperion for rockets

URL: [28]

Comment: Lack of dispersion makes especially for air units hard to hit targets. Not realistic and bad for gameplay.

Disable auto locking of infantry launchers or reduce automatic lock area

URL: [29]

Comment: While both should be realistic, with the visible locking cursor it makes them too easy to use and strong. Could be solved with the option to hide the locking cursor, or make (some) launchers require RMB use to lock onto a target.

Improve countermeasures and warning system

URL: [30]

Comment: cmImmunity should be tweaked, but AI use needs be improved as well as MP issues.

Missiles don't lead moving optical/laser targets

URL: [31]

Comment: Very important for manual guidance of missiles.

SACLOS guidance unrealistic

URL: [32]

Comment: Very important for manual guidance of missiles.

ballisticsComputer calculation uses inverted target lateral velocity when facing south

URL: [33]

Comment: This bug should be finally fixed.

Locking of _guided missiles_ does not work as pilot without gunner

URL: [34]

Comment: Useful for lower difficulty settings.

Add additional "preparation" time when selecting launchers

URL: [35]

Comment: To make infantry launcher use non as simplistic/gamey.

Make fuseDistance config entry working for Rockets/Missiles/RPGs

URL: [36]

Comment: Useful tweak.

Add more damagable systems and indicators for fixed-wing-aircraft

URL: [37]

Comment: Should be present already in A3, yet further tweaks/improvements would be useful.
