/*
 * Author: nou, jaynus, PabstMirror
 * Called from FiredBIS event on AllVehicles
 * If spall is not enabled (default), then cache and only track those that will actually trigger fragmentation.
 *
 * Arguments:
 * 0: gun - Object the event handler is assigned to <OBJECT>
 * 4: type - Ammo used <STRING>
 * 6: round - Object of the projectile that was shot <OBJECT>
 *
 * Return Value:
 * Nothing
 *
 * Example:
 * [clientFiredBIS-XEH] call ace_frag_fnc_fired
