It was claimed in this comment that companions' weapons don't degrade in Fallout: New Vegas. Is that true? What about companions' armor? Does the difficulty of the game influence this? What about hardcore mode?
This question is not about companions' default items that can't be taken away. It's about items that you add to your companions' inventory manually.

This was changed several patches ago and I never updated my answer.
As of a patch some time ago, companions' weapons degrade per attack at the same rate as the Courier's.
Armor degrades based on damage taken.
