I'm trying to move Cubes independently.

I've created a small class of five cubes and I want to be able to move them all independently and at the same time. So far, I can move all of them to the same exact series of waypoints, I simply "right click" and can add any number of waypoints.

BUT...I want to move them to different waypoints and I want to control each cube separately. I'm having a heckuva time figuring this out. Thanks for any suggestions.

 void Start ()
 {
     for (int i = 0; i < 5; i++)
     {
         ///// Creates Member of Class
         CombatUnit blueUnit = new CombatUnit();

         ///// Creates Cube
         var cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
         
         ///// Location of Cube selected randomly
         cube.transform.position = new Vector3(Random.Range(5f,25f), 0,Random.Range(5f,25f));

         ///// Adds movement script to cube
         cube.AddComponent<MoveTest>();
     }
 }

 // Update is called once per frame
 void Update() { }

 public class CombatUnit
 {
     public int UnitID { get; set; }
 }

}
