This has something to do with has something to do with the US & Mexico, or at least takes place in the southern United States and into Mexico. Someone on the chat ran the IP, it came up as Fort Huachuca. That is an Army fort In southern AZ very close to the border. In the transcripts here http://pbc.wikia.com/wiki/Points_of_Interest[1] There is a lot of "Army speak". In those he also mentions L.A and a contact known as Mendoza. Another Hint is that it takes place in this area is he mentions the Tlaxcala office. Tlaxcala is a state in Mexico. Another big hint is he says "I think we should learn the local customs".
There are other references to the southern United States & Mexico if you keep looking.
