How to destroy GameObject & Instantiate new one after a while?

I want to resurrect the tank after being destroyed by bullets and restore its original attributes. But the following code will make the tank lose all its attributes after resurrection.How can I modify it to meet the conditions and allow the tank to resurrect indefinitely?

public class Bullet : MonoBehaviour {

GameObject tank1; GameObject tank2; public int bullet; bool isDestroy;

// Start is called before the first frame update void Awake() { tank1 = GameObject.Find("Tank1"); tank2 = GameObject.Find("Tank2"); }

void OnTriggerEnter2D(Collider2D other) { if (bullet == 1) { if (other.tag == "Wall") { Destroy(this.gameObject); }

if (other.tag == "Tank2") { Destroy(this.gameObject); Destroy(other.gameObject); tank2= Instantiate(tank2, transform.position, transform.rotation); } }

else if (bullet == 2) { if (other.tag == "Wall") { Destroy(this.gameObject); }

if (other.tag == "Tank1") { Destroy(this.gameObject); Destroy(other.gameObject); tank1 = Instantiate(tank1, transform.position, transform.rotation); } }

} }
