Random.range Selects the same target? (all turrets choose same target???) (Taget is not selected at random?))

hey gang, just wondering why every turret in my scene with the same gun script targets the same object, when its using random.Range So each turret sound be selecting a random object in array?

for some reason every turret targets the same same "TeamOne" or ""TeamTwo" object and its alwys the first object in the array every time I run the game?

 using System.Collections.Generic;
 using UnityEngine;
 
 public class antiFighterGuns : MonoBehaviour
 {
 
     public GameObject[] TargetTs;
     public GameObject TargetT;
     int index;
     public float GunRange = 1200;
     public float nextFire;
     public float fireRate = 0.5f;
     public GameObject LaserObj;
     float Distance;
 
     public bool AllyGun;
 
    
 
     // Update is called once per frame
     void Update()
     {
         if (TargetT == null)
         {
             if (AllyGun == true)
             {
                 TargetTs = GameObject.FindGameObjectsWithTag("TeamTwo");
                 index = Random.Range(0, TargetTs.Length);
                 TargetT = TargetTs[index];
             }
 
             if (AllyGun == false)
             {
                 TargetTs = GameObject.FindGameObjectsWithTag("TeamOne");
                 index = Random.Range(0, TargetTs.Length);
                 TargetT = TargetTs[index];
             }
         }
 
         if (TargetT != null)
         {
             transform.LookAt(TargetT.transform);
             Distance = Vector3.Distance(TargetT.transform.position, transform.position);
         }
 
         if (Distance > GunRange)
         {
             TargetT = null;
         }
 
 
 
 
 
         if (Time.time > nextFire && TargetT != null)
         {
             nextFire = Time.time + fireRate;
             Instantiate(LaserObj, transform.position, transform.rotation);
         }
 
     }
