Mambajoa is an island in Southeast Asia.
A newscaster mentions that the weather there had been unseasonably cold for Southeast Asia, but that it did not deter the United States' 5th Infantry Regiment stationed on the island, who were battling communist forces.
Mambajao is mentioned only in Fallout 4.
- Newscaster: "It would also appear our troops stationed overseas are experiencing some unusual weather, as well. On the Island of Mambajao the nights are cold. Unseasonably so for Southeast Asia. But for the 5th Infantry, that's as comfortable as an Autumn jamboree. All the easier for our mechanized hellcats to drive any screaming Commie meamies right into the Bohol Sea."
