David Dockmaster Dunn is a UEG government official, serving as the Earth Minister of Information in 2552. That year, during the Battle of Earth, Dunn issued a general alert to the civilians of New Mombasa about the Covenant attack and the evacuation. His propaganda-laced message can be seen on view screens throughout downtown New Mombasa.
- He is likely named in honor of Bungie Employee David Dunn.
- Unlike the other signs found in Metropolis, the sign with Dunn's message is destructible and will explode violently, similar to the signs seen in the Halo 2 E3 Demo.
