Balad Burn
Smoke billows in from all sides as Army Sgt. Richard Ganske, 84th Combat Engineer Battalion, pushes a bulldozer deep into the flames of the burn pit in Balad, Iraq, Sept. 24, 2004. On combat deployments, service members may be exposed to toxins, such as those from burn pits. The Defense Department is looking for better ways to track these exposures.
