Sgt. Anthony Vasquez, Company A, 1st Battalion, 15th Infantry Regiment, 3rd Heavy Brigade Combat Team, 3rd Infantry Division, provides security Feb. 16, 2010, as leaders of the 1st Bn., 15 Inf. Regt., the Diwaniyah Provincial Reconstruction Team and members of the Director General take soil samples in Diwaniyah, Iraq. The samples were taken to determine if land was suitable for "tunnel houses," low-tech versions of greenhouses. This is the first step toward what is hoped to be a lasting source of income for many farmers in Diwaniyah.
