OnControllerColliderHit -> GetComponent on collided object not working

I have been researching this for 6 hours. Slept on it, another 2 hours and still no luck. I have never felt so defeated; this problem has to be something so simple and stupid! Here's the skinny:

I have a player GO that is a modified CharacterController ("Player"). It is the parent of a small sphere GO that has a SphereCollider on it ("Weapon"). Any time I try to collect the Enemy script from collisions, I pop 3 generic errors.

I am testing collisions against a Cube primitive that has a BoxCollider and a Rigidbody ("Enemy"). It also contains a script (Enemy.cs) with the basic badguy functions.

Codewise on the Player (parent, CharacterController):

  private Enemy enemy;
  void OnControllerColliderHit(ControllerColliderHit hit) {
         if (hit.gameObject.tag == "Enemy") {
             enemy = hit.gameObject.GetComponent(Enemy);
             enemy.TakeDamage(25);
         }
      }

I have also tried:

 void OnControllerColliderHit(ControllerColliderHit hit) {
        hit.gameObject.GetComponent(Enemy).TakeDamage(25);
      }

Throws these errors on the line where I try to GetComponent():

• Error CS0119: Expression denotes a type', where a variable', value' or method group' was expected

• Error CS1502: The best overloaded method match for UnityEngine.GameObject.GetComponent(System.Type)' has some invalid arguments - **Error CS1503:** Argument #1' cannot convert object' expression to type System.Type'

I get the same errors also trying OnCollisionEnter() attached to the Weapon GO. I learned that the Parent GO has to handle collisions for its children, which led to dropping the OnControllerColliderHit() onto the Player.

Thanks for taking the time to read this. I appreciate any help you can offer. I'm thinking about just not worrying about collisions between the Player and anyone else, un-childing (bastarding?) the Weapon GO and then just enabling it around the player during its animation so it can handle its own collisions.
