Can't Locate gameobject in array

As the title states, i am using a for loop to try and instantiate a gameobject inside of an array, but the if statement i have checking for the tag of the game object does not actually work,

my code is posted below, i have placed debugs in certain places and i have used comments to highlight the problem area and before someone says it, i have octuple checked, there is in fact a game object at that location and if i use an integer to define the specific spot in the array the game object i want to spawn is at, it works, it is just the for loop that i have met difficulty with, i can spawn the object if i define the spot in the array i want to instantiate with an integer, but i cannot make the code dynamic and search for the game object inside the code, that is my objective here, to make the code dynamic

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Mspawn : MonoBehaviour {
 public Button button;
 public BoardManager boardManger;
 
 void OnEnable(){
     if (Input.GetMouseButtonDown(0)) {
         button.onClick.AddListener (SpawnUnit);
     }
     
     
 }
 void awake(){
     boardManger = GetComponent<BoardManager> ();
 }
 void SpawnUnit()
 {
     Debug.Log ("Testing...");
     for (int i = 0; i < boardManger.PlayerUnits.Length; i++) 
     {
         Debug.Log ("Testing...(1)");
         if (boardManger.PlayerUnits[i] == GameObject.FindWithTag("PlayerSoldierMarksman"))
         {
 // the code has great difficulty entering this if statement, 
                 Debug.Log("Testing complete");
                 Instantiate (boardManger.PlayerUnits[i], new Vector3 (1, 1,0f), Quaternion.identity);
             }
         }
     }
 }
