It is represented by a red and silver signpost with a Rocket Launcher in front of it.
Trivia
- An easy way to do this on single-player is to give your rocket launcher to a marine, collect the rocket launcher behind the tank wall at the start of the level, and give that to another marine. Get into the scorpion and let them get on. Then go to where the first wraith was and let the other two marine hop on. They both have rocket launchers. So you basically have a moving fortress. A Scorpion, a guy in a turret, and 4 rocket troopers......The achievement should be yours in at least 2 mins......
- Another way is at the beginning of the level, behind the empty Scorpion there is a crate. Behind that crate is a rocket launcher with four more rockets. Although, this still means you must get multiple kills with each rocket.
- When you get to the point in the level where there is a arrow over your teammate Dutch, there is a marine with a rocket launcher with four rockets on top of the building where you find the broken gauss turret beacon, though he will sometimes be killed by the Wraiths.
- There is a total of ten rockets altogether in this level so you only need to get one kill with each.
