More than 400 soldiers of the 3rd Battalion, 157th Field Artillery got a noisy send-off from a couple thousand of their closest friends and family. It is the largest deployment of the Colorado Army National Guard since World War II, when the 157th helped liberate the Nazi concentration camp in Dachau, Germany. The unit was leaving "to put the seal on victory in Iraq," said Maj. Gen. H. Michael Edwards. "I want you back safe and sound 12 months from now," Edwards told the soldiers.
