"I'm telling you, if this doesn't kill that giant metal daddy; I don't know what will."
The M1A1 Bazooka was a type of rocket launcher in Rapture.
Like the Greaser, the M1A1 was brought down by smugglers to Rapture. Though fairly large, it was easy for the smugglers to hide it since their were large crates hanging around the city. During the Civil War in Rapture, the M1A1 caused major damage to the city as rockets would hit the pressure proof glass; and water would flood into the buildings. Even Rapture's advanced metal locking systems were no match for the destruction the M1A1 caused.
