# Arma 3: Countermeasures

Countermeasures, detection of locking, tracking and missiles in flight.

### Mechanics

> [!NOTE]
> Ground vehicles with Incoming Missile Detection ability use the same SENS display as air vehicles to display threats. See the **[Custom Panels](../topics/Custom_Info.md)** page for details.

|  |  |  |
|---|---|---|
| Different types of targets on the radar | Player's vehicle is being locked by an enemy | ammo [weaponLockSystem](../topics/Targeting_Config_Reference.md#weaponlocksystem)<br>*matches*<br>vehicle [lockDetectionSystem](../topics/Targeting_Config_Reference.md#lockdetectionsystem) |
| Different types of targets on the radar | A guided munition is homing on the player's vehicle | ammo [weaponLockSystem](../topics/Targeting_Config_Reference.md#weaponlocksystem)<br>*matches*<br>vehicle [incomingMissileDetectionSystem](../topics/Targeting_Config_Reference.md#incomingmissiledetectionsystem) |

### Configuration

The following properties of Ammo, Weapon and Vehicle can use basically any [bitmask value](https://forums.bistudio.com/topic/189734-targeting-improvements/page-13#entry3062179) (See also [BIS_fnc_bitflagsCheck](../functions/BIS_fnc_bitflagsCheck.md)).

BI uses the following convention

|  | ammo | ammo (countermeasure) | weapon | vehicle |  |
|---|---|---|---|---|---|
| System | [weaponLockSystem](../topics/Targeting_Config_Reference.md#weaponlocksystem) | [weaponLockSystem](../topics/Targeting_Config_Reference.md#weaponlocksystem) | [weaponLockSystem](../topics/Targeting_Config_Reference.md#weaponlocksystem-2) | [lockDetectionSystem](../topics/Targeting_Config_Reference.md#lockdetectionsystem) | [incomingMissileDetectionSystem](../topics/Targeting_Config_Reference.md#incomingmissiledetectionsystem) |
