Combat Script

The foundation for this code is not mine however I have added some elements. I want to be able to target all enemies in the array and then be able to attack them. What do I need to modify or add to this code to do so? Thanks in advance.

 var enemyTarget : GameObject[];
 var range : int = 2;
 var countDown : int = 0;
 var coolDown : int = 2;
 var swordOut : boolean = false;
 
 function Update ()
 {
     Targets();
     if(swordOut)
     {
         if(countDown > 0)
         {
             countDown -= 1 * Time.deltaTime;
         }
         if(countDown < 0)
         {
             countDown = 0;
         }
         if(Input.GetKeyUp(KeyCode.E))
         {
             Swing();
         }
     }
 }
 
 function Targets ()
 {
     enemyTarget[0] = GameObject.FindWithTag("enemy");
     enemyTarget[1] = GameObject.FindWithTag("enemy");
 }
 
 function Swing()
 {
     var distance : int = Vector3.Distance(enemyTarget.transform.position, transform.position);
     var dir = (enemyTarget.transform.position - transform.position).normalized;
     var direction = Vector3.Dot(dir, transform.forward);
     
     if(distance <= 3)
     {
         if(direction > 0)
         {
             enemyTarget.GetComponent(enemyHealth).currentEnemyHealth -= 35;
         }
     }
 }
