Word that describes either a team or a single player

What is a good word for describing an entity (usually in a sports event) that can consist of one or more players?

The idea is to give a name to a class (in code) for such a group (or player) within a game.


In some contexts it doesn't sound as natural as team, but side fits.

In this game there are three sides.

Or

Each side has one or two players.

Or

Each side tries to keep the other sides from collecting the erychronolite before the magnum-sploty awakes.

But as oerkelens says, if you're naming a class in code, I should think team would be better, since it's not as ambiguous a word as side.


Opponent.

The American Heritage Dictionary says

  1. One that opposes another or others, as in a battle, contest, or debate: a political opponent.
