Phobos (2016)

Phobos is a location in Doom Eternal. It is one of the moons of Mars (2016) which Doom Slayer will visit during his campaign during the game.

In Doom (2016) Phobos (and Deimos) are used as mining stations, although it is never stated, or implied that any outbreaks, or military operations occurred there.

Gameplay videos show that at the point the Doom Slayer shows up an demon invasion has begun, and there are still living human scientists and guards in the bases command center. Doom Slayer is shown taking a weapon from a scared guard, and exits the command center to kill the invading Demon's. Other elements of the base include large defense cannons.
