To defeat your enemies, know their weaknesses! You can view a target's specific damage resistances in V.A.T.S.
While this will reveal resistances for an enemy (in addition to a crossed-out symbol for immunities) it will not display any special characteristics. The main example of this is that ghouls are listed as having 1000 radiation resistance, when in truth they have a special effect that lets radiation damage heal them, making the resistance moot.
