I'm just wondering if Fallout New Vegas is like Skyrim, where wearing an armor on one body part will protect other body parts (regardless if armor is worn on that body part).
In FNV, do body armors have any effect on the head? Will it be better to use hollow point ammunition (does more damage to unarmored opponents) on an enemy with body armor, but no helmet or head armor or other head apparel when targetting the head?
