+# Vehicle EMP
+
+## EMP Duration
+
+The calculated duration is given by:
+
+```sqf
+ _effectiveDuration = _empDuration * (1 + ((-_empResistancePercent)/100));
+```
+
+or
+
+```c
+Effective Duration = Ammo Duration * (1 + (-Resistance/100))
+```
+
+Therefore:
+
+- A resistance of < 0 will produce an INCREASE in duration.
+- A resistance of > 0 will produce a DECREASE in duration.
+- A resistance of 0 will produce the same duration defined on the ammo.
+- A resistance of 100 will produce a 0 duration (no effect).
+- A duration of 0 will always result in no effect.
+
+> An effective duration of 0 is assumed for calculated durations < 1 for performance.
+
+## Configuration Properties
+
+### EMP Enabled
+
+Specify if the given ammo has an emp effect on vehicles.
+
+Where to define: `CfgAmmo -> Ammo`.
+
+`rd501_emp_vehicle_enabled=1`
+
+Default: `0`
+
+### EMP Max Duration
+
+You can specify how long a given set of ammo can disable a vehicle for (at maximum). Resistance will reduce this.
+
+Where to define: `CfgAmmo -> Ammo`.
+
+`rd501_emp_vehicle_duration=number`
+
+> `number` is the number of seconds this ammo will disable a vehicle for.
+
+> Note that this is only factored in, if a vehicle has a resistance of 100%, then the emp will not do anything. 50% resistance will halve the duration etc.
+
+Default: `10`
+
+### EMP Resistance
+
+You can specify a vehicles resistance (as a %) to the effects of EMP.
+
+Where to define: `CfgVehicles -> Vehicle`.
+
+`rd501_emp_vehicle_resistance_percent=number`
+
+> `number` is the whole number percentage (max 100, min unbound) which will be applied as a reduction to the given ammo's EMP duration.
+
+> `rd501_emp_vehicle_resistance_percent=100` is effectively disabling the effects on emp on the vehicle. (Immunity)
+
+Default: `0`
