Bravo Team was a squad of marines stationed on Mars City in Doom 3. When the demons invaded Mars, Bravo Team was one of the few groups of marines to survive the initial wave of the attack. The player spends the first third of the game attempting to meet up with Bravo Team. However, Bravo Team is ambushed by a group of Imps and Wraiths at the Enpro Plant, and by the time the player reaches their location, the entire team has been wiped out, save for a single, badly wounded marine. The surviving marine from Bravo Team gives the player a special transmission card that will allow the player to send a distress call to Earth's Fleet. Moments later, the lone survivor is attacked and killed by a Wraith.
There are 2 Bravo Team members that have their name given. One is named Sam and another is named Lee.
