Shooter Style Game - Shooting Strategy

I am working on a 3D-shooter prototype. I have all the models (with animations) in place, but am not sure how to proceed further with the shooting strategy.

Since I want to highlight the area where enemy gets shot (head, chest, legs, etc).

What strategy should i use to achieve this ? – (would a bunch of Box Colliders for each part be enough?)

Since the enemies can move and attack – would the above method work since the arm/legs are in motion and might animate outside the Collider box?

Use colliders that are children to the bones as hitboxes. They don’t have to be boxes, they can be any shape.
