Accessing Enumeration from another script issue

Hello! Im trying to read enum type from another script but im getting this error

 Type `Mob.Defence' does not contain a definition for `defenceType' and no extension method `defenceType' of type `Mob.Defence' could be found (are you missing a using directive or an assembly reference?)

First Script.

 using UnityEngine;
 using System.Collections;
 
 public class Mob : MonoBehaviour {
     
 [System.Serializable]
     public class Defence
     {
         public float DefenceCount;
         public DefenceType defenceType;
 
         public enum DefenceType
         {
             Armor,
             EnergyShield,
         }
     }
 
 
     public Defence defence;
 }

Second Script.

  using UnityEngine;
     using System.Collections;
     
     public class Weapon : MonoBehaviour {
     
     // Update is called once per frame
         void Update ()
         {
             switch(target.gameObject.GetComponent<Mob>().defence.defenceType)
             {
               case Mob.Defence.DefenceType.Armor:
               Debug.Log("Mob DefenceType is Armor");
               break;
             }
             }
     }
