In Iraq, Sergeant 1st Class Martin Stadtler had nothing. He was stationed near Mosul, at a base that covers 24 square kilometers. Surrounding the base was a wall, and at intervals along that wall stood watchtowers. Those towers were improvised; they were large concrete water pipes, stood on their ends.
Inside each tower is a pair of soldiers. They’re watching for insurgents. To communicate with the home base, they had standard-issue tactical radios. Unfortunately, these radios couldn’t reach home base — the base was too big. Soldiers had to play a game of Telephone to reach the base: one tower radios the next until they are finally in range of the home base. Obviously, this would not do.
