The scene with the hummer and BOS soldiers - does anyone know the title of the song in the background? Thanks!

Unfortunately i could not find anything about the Fallout Tactics soundtrack, but you might want to check it out here : http://www.fallout3nexus.com/downloads/file.php?id=108
Seems someone uploaded the songs from Tactics, you might recognize it

Just a thought (I don't have the game) but I would expect it to be mentioned on the in-game credits.
