Having Multiple Controllable FPS Units Selected From A Singular RTS Mode?

Hello

This is a problem thats been wracking my head for a month now due to how hard it is for my head to wrap around the underlying concepts. My Game is set up in a way where I can control units via an RTS mode but also select via mouse click using ScreenPointToRay in order to assume controll of said unit. The second part is where im having a bit of trouble concerning the topic of multiple units where i can control any one of the multiple. I know it has something to do with arrays and possibly tags but appart from that I have no Idea

This is the code in its current state

 #pragma strict
 
 var camera1 : Camera;
 var camera2 : Camera;
 var target : Transform;
 var target2 : Transform;
 var objprefab : Transform;
 private var objspawned : Transform;
 
 function start () {
     if (Input.GetMouseButtonDown(0) && (camera1.enabled == true)) {
         Debug.Log("Clicked ");
         var hit: RaycastHit;
         var ray: Ray = camera1.ScreenPointToRay(Input.mousePosition);
         
         if (Physics.Raycast(ray,hit)) {
             Debug.Log("Clicked " + hit.transform.name);
             if (hit.transform.gameObject == target) {
                 Debug.Log("targ");
                 camera1.enabled = false;
                 camera2.enabled = true;
                 Cursor.visible = false;
                 Cursor.lockState = CursorLockMode.Locked;
                 
                 (GameObject.Find("BaseChar").GetComponent("FirstPersonController") as MonoBehaviour).enabled = true;
                 (GameObject.Find("StratShell").GetComponent("RTSCam") as MonoBehaviour).enabled = false;
             }
 
             else if (hit.transform == target2) {
                 objspawned = Instantiate (objprefab, hit.point, Quaternion.identity);
                 GameObject.Find("BaseChar").GetComponent.<AIPath>().target = objspawned.transform;
                 Destroy (GameObject.Find("Pin(Clone)"), 0.1f);    
             }
         }
     }
 }

camera 1 is the rts camera camera 2 is the fps camera target is the unit target 2 is the terrain allowing for me to drop a 'pin' that astar then picks up and sets as the transform for pathfinding objprefab is the pin objspawned is a private var that does other things i cant remember the specifics of

i think thats everything you'll need to help me. where can I find some referencing or some code samples thaat would allow me to employ multiple units?

Thankyou so much in advance :D
