Sgt. Charles Crowley and team repair a 5-inch local sewer pipe at Camp Victory in Heart, Afghanistan. “The local sewer pipe was equal to the SDR pipe used in the States. The only problem is they don’t have any fittings, and you have to heat the pipe to make your bends and fittings,” Crowley says.

“My company is the first line of defense for the camp,” he wrote us. “I normally work the night shift. I spend the night watching out of a tower to provide security to the base camp, making sure that everyone is safe.”
Crowley has also gone on joint patrols with the Afghanistan National Army and helped support the country's first elections. Last October, he was assigned to work with an Illinois artillery unit and the Mongolian National Army to help train the Afghan troops how to use a Russian D30 122mm Howitzer.

As you can see from one of the pictures, he hasn't left his plumbing skills at home either. In fact, while on patrol he's met local plumbing supply companies and a manufacturer of hand pumps.
