Away team

An away team is a team of people usually from a starship who conduct special missions, the majority of these on alien terrain.

According to Starfleet regulations, the captain was prohibited from leading any away missions, but through the years more and more captains decided to "overlook" this regulation. In special circumstances, such as a first contact mission, the captain was required to lead the team.

Uniform
The away team commonly wore different uniform on away missions to that worn during normal duty.
