REAPER_ImprovedAI

Key Features
- Improved reactions to incoming and distant gunfire
- Exposed soldiers actively search for nearby lateral cover
- Coordinated fire-and-movement tactics with separate moving and covering elements
- Support weapons remain in covering positions longer
- Increased use of enterable buildings and authored interior combat positions
- Controlled distribution between interior and exterior cover to prevent entire groups from crowding into one building
- Combat cover positions are released after 150 seconds so units do not camp one location indefinitely
- A minimum spacing between occupied cover positions reduces unit stacking
- Improved Defend behavior using observation, gate and cover positions
- Upright combat movement instead of constantly moving while crouched
- More intelligent frag grenade usage against covered targets and clustered enemies
- Group-wide grenade coordination and cooldowns
- Empty soldiers search nearby casualties for compatible, non-empty magazines
- Ammunition recovery is limited to three magazines per visit and restores the matching firearm
- Defensive smoke usage after casualties or leader loss
- Smoke grenades are avoided inside occupied buildings
- Temporary morale effects after casualties, heavy pressure or leader incapacitation
- Reduced fire rate while a group is shaken, followed by gradual recovery
- Improved medic coordination with fewer duplicate treatment attempts
- Non-critical treatment may be delayed under extreme threat
- Distant sound investigations are limited to one fireteam instead of attracting the entire group
- AI can close ordinary doors after passing through them
- Door closing respects nearby followers, vehicles and blocked doorways
- Stuck soldiers can toggle a nearby door to clear their path
- Player-issued commands receive maximum priority and override autonomous cover relocation
- Improved vehicle and helicopter boarding behavior
- Fixes a Vanilla AI boarding activity lifecycle issue

Performance
The mod is designed to remain lightweight:
- No global update loop
- No continuous world scanning
- No per-frame entity searches
- Uses existing Vanilla AI events, cover queries, smart actions and behavior systems
- Corpse inventory searches run only after a real ammunition failure

Compatibility
- Standalone mod with no dependency
- Compatible with Vanilla AI groups and player-commanded AI groups
- Does not globally increase AI vision range or weapon engagement distance
- Buildings require valid navmesh, cover positions or authored smart actions
- Other mods overriding the same Vanilla AI methods may affect compatibility depending on load order
