This page contains all information about Arma 3`s artificial intelligence, short AI.

AI Skill

The AI is characterized by a set of sub-skills. Each sub-skill is influence by one of the following:

Each sub-skill is then interpolated with the values set in CfgAISkill.

Additionally the AI skill is also influenced by the global setting in the difficulty menu.


Sub-skills are a set of parameters ultimately defining the individual AI unit performance in the game.

Sub-Skill Effect Influence
  • Affects how well the AI can lead a target
  • Affects how accurately the AI estimate range and calculates bullet drop
  • Affects how well the AI compensates for weapon dispersion
  • Affects how much the AI will know to compensate for recoil
  • Affects how certain the AI must be about its aim on target before opening fire
  • Higher value means the AI can lead a target better
  • Higher value means the Ai can estimate range and calculate bullet drop more precicely
  • Higher value means the AI can compensate weapon dispersion better
  • Higher value means the AI can control the recoil better
  • Higher value means the AI needs to now less to open up fire
  • Affects how quickly the AI can rotate and stabilize its aim
  • Higher value means the AI can rotate and stabilize its aim faster
  • Affects how quickly recognized targets are shared with the group
  • Higher value means the AI can report targets faster
  • Affects unit's subordinates' morale (Higher value = more courage)
  • Higher value means the AI has got more courage
  • Disabled in Arma3
  • Disabled
  • Raw "Skill", value is distributed to sub-skills unless defined otherwise. Affects the AI's decision making.
  •  ?
  • Affects the delay between switching or reloading a weapon
  • Higher value means the AI can switch or reload weapons faster
  • Affects the AI ability to spot targets within it's visual or audible range (Higher value = more likely to spot)
  • Affects the accuracy of the information (Higher value = more accurate information)
  • Higher value means the AI is better at spotting targets
  • Higher value means the AI will collect information about targets more precisely
  • Affects how quick the AI react to death, damage or observing an enemy
  • Higher value means the AI will react faster to death, damage or enemies
  • Affects how steadily the AI can hold a weapon (Higher value = less weapon sway)
  • Higher value means the AI will be more precise


CfgAISkill is a set of arrays, related to AI Sub-skills, defining the interpolation curve of each of the sub-skill.


Interpolation with vanilla A3 CfgAISkill

In {w, x, y, z} value from (w,y) gets interpolated into (x,z) spotDistance[] = {0,0.2, 1,0.4}; value in a range 0-1 will change into value in a range 0.2-0.4. setSkill ["spotDistance", 0.5] results in skill "spotDistance" returning 0.3


More than 2 pairs of defining values can be used (minimum is 2 pairs).

The values are used to interpolate on run-time, so even after setting sub-skill by script command it will be interpolated and bound by this array.

Defaults for Arma 3

aimingAccuracy[] = {0, 0, 1, 1};
aimingShake[] = {0, 0, 1, 1};
aimingSpeed[] = {0, 0.5, 1, 1};
commanding[] = {0, 0, 1, 1};
courage[] = {0, 0, 1, 1};
endurance[] = {0, 0, 1, 1}; Has been disabled in Arma 3
general[] = {0, 0, 1, 1};
reloadSpeed[] = {0, 0, 1, 1};
spotDistance[] = {0, 0, 1, 1};
spotTime[] = {0, 0, 1, 1};
