A captain's assistant is commonly referred to as a first mate or second mate, depending on the hierarchy within the crew. They assist the captain in overseeing the ship's operations, navigation, and crew members.
Co-captains share the tasks of being the leader of a team equally; they are both captains at the same time. This is somewhat different to an assistant captain who helps the main captain do their job, or a vice-captain who stands in when they are absent or busy.
Brooks Laich, Nicklas Backstrom, Mike Knuble, and Troy Brouwer are all listed as assistant captains on the Washington Capitals roster. However, only two assistant captains are allowed to wear the assistant captain patch in a game. Laich and Backstrom are usually the two that sport the "A's" on their chest in Capitals' games.
