Page 35, Bodyguard rule text:

A unit with this ability adds 1 to the Protection of
allies it is in contact with. This ability cannot raise
the Protection score of the allied units above 3 (if the
ally’s Defense is already greater than or equal to 3, it
keeps its regular Defense). This bonus is applied after
all other bonuses: it is applied after any cover bonuses
(or Resistance).

Which is it; Defense or Protection? I've always played Protection, but either way, it needs corrected.

Protection.
