        _spawn     - Positions to spawn attackers or radius around target                   [ARRAY, NUMBER, defaults to 200]
        _count     - Amount of waves                                                        [NUMBER, defaults to 10]
        _delay     - Delay between waves                                                    [NUMBER, defaults to 45]
        _condition - Condition code, spawning will stop if it will return false             [CODE, defaults to {true}]
        _ao        - Area, if provided spawned units will have a chance to become avalanche [ARRAY or STRING, defaults to ""]

        _onSpawned - Callback function to execute on each spawned group (passed as _this)   [CODE, defaults to {}]
        _completionRadius   - Attack waypoint completion radius                             [NUMBER, defaults to 20]
        _completionStatment - Attack waypoint statment, if ommited default Tracker/Avalanche is applied on completion [STRING, defaults to nil]

    Example:
        [markerPos "vn_wp1", 150, 3, 15] call vn_ms_fnc_tracker_attackArea;
