Mad preacher with the nukes
There is a man standing on the second floor of a building in an alleyway near the headquarters entrance. The alley has been rigged with mines and nukes that he detonates if you try to get close to him. There is a hostage on one end of the alley, who you can talk to. If you are looking at the mad preacher when he detonates, he waves at you.

If your stealth is high enough, you can sneak through and pick up the frag mines and multiple mininuke. Not advisable without the Light Step perk. If you remove all the nukes and mines off the ground, the Preacher can still cause detonation if he sees you in the alley. You can talk the hostage into confronting the man, but he gets blown up in the mine field. Only other solution appears to be sniping the loudspeaker guy from a distance. He also yells "trees! trees! to the north! but there deadly, and they wil be consumed by the GREAT FAT WORM!!!",He is reffering to oasis. He also appears to be in great pain yelling "the sun why does it burn MAKE IT STOP!!".
