The Expeditionary Medal, or "Exped" or "Exp", is one of the simplest medals to earn. Simply complete a campaign with each member of the team using a different character class. This has the advantage of making sure every role is filled. It is possible to get this medal when playing with classes that share CP such as tech and assault. As with other medals, ranks 1 and 2 can be achieved in Recruit or Normal, the third on upwards must be earned in Nightmare.
- 1 Medal Point = Win a game with 8 players with everyone playing as a different class.
- 1 Medal Level = 10 Medal Points (Win 10 games with 8 players and each player choosing a different class.)
