The characters are able to get a lift into Haierburg on the back of a supply truck that has come to collect cargo. "Who'd you piss off to get sent here?", the driver asks. Abandoning the "soil sample" gambit, they say there were sent to meet Brian Cooper (Reade's contact). "Most likely find him in the cantina after about 4", says the driver, and with that, the characters head to the bar/inn.
Haierburg is a bit ramshackle, filled with buildings that clearly weren't meant to be permanent, but now seem well lived in, each adorned and "improved on" by its individual inhabitant(s). The only real solid structure in the town is a concrete building next to a large communications antenna and surrounded by a barbed wire fence. With few off-road vehicles and trucks are parked nearby, the characters instantly recognize this as a typical military support installation that's hung around for much longer than intended.
Once in the bar, the innkeeper, Finley Cooper (no relation to Brian), gives them the name of the local doctor, Hank Armiger, and tells them that Brian Cooper will likely be in later in the afternoon. The characters decide to wait, and at around 4pm he arrives on schedule. Cooper explains the situation; the raider problem just needs to "go away" and no one is going to question the method. He agrees to lend them a vehicle and gives them the approximate location of the raider camp. With that, the characters head off on their appointed mission.
Traveling about half a day across the desert, the characters ditch Brian's vehicle about 3k from the camp site to avoid detection and proceed on foot from the East. On closer approach they are able to survey the encampment which consists of a few "temporary" buildings and two larger hangars nestled against a large rock outcropping. South and West approaches to the camp are protected by the outcropping itself, while the North and Eastern approaches are guarded by two heavily constructed fences. Each fence terminates in a small bunker, the passage between them forming the only entrance to the camp. A few vehicles are parked outside with a few people milling about, but the character pay particular attention to a gun emplacement on the rock at the Southern end of the East fence.
Waiting until just before dawn, the characters are able to stealthily approach the Southern gun emplacement and enter the camp. Shots are eventually exchanged as Fred encounters raiders in one of the hangars, and a gun battle ensues between the remainder of the outlaws and the rest of the party. As the sun rises, the camp is strewn with the bodies of raiders who have fallen to our seasoned veterans whose mission seems to have been accomplished.
