Weapons, Armor and Psychology

Alright, here's the point of this Conversation.

Clearly some weapons and armor have advantages over others yes we all know this.

But what about the Psychological aspect, what would be the reason for using certain weapons or wearing certain armor's.

Think about it, if you pick up a chainsaw it's because you associate the sound and look of a chainsaw with POWER, extreme killing power, it would instill you with confidence.

in short think of a weapon or Armor that would instill you and those around you with confidence just to see someone using it.

Personally i say the most prominant are the Chainsaw and plate armor... now imagine someone in both?...
