Where/how can you see an enemy's level in Fallout 4?

I keep seeing all these questions referring to enemy levels in Fallout 4 and how people killed a monster or enemy at level XX - how do you know/detect what level the enemy is? I have looked in settings and over the perk list and saw nothing immediate about enemy levels.


The level 3 Perception perk "Awareness" will allow you to see the enemy level as well as their resistances when viewing the enemy through V.A.T.S.:

V.A.T.S showing awareness
