From S4 at War:

The “port-o-pottys” I need are contracted by KBR. They clean and maintain them for us. I need to put them on the Iraqi Army portion of our FOB for about 5 days (the Iraqi Army portion of our FOB is connected to our side and just as safe as our side). But KBR won’t leave the contracted sections of our FOB so if I move the latrines 5 meters away then they won’t clean them. Solution?? Let one of my Soldiers drive the truck the 5 meters and clean the latrines, then return it. Can’t happen, KBR won’t allow it. In order to make this happen we have to put 4 port-o-pottys on a trailer and drive it back and forth the 15 feet to cross an imaginary line in the sand.
