President Obama's recent decision to pull U.S. troops out of Iraq has many military families breathing a huge sigh of relief. That's true for Tom and Mary Ward, whose son Sean has spent two Army tours in Afghanistan and two in Iraq. They're thrilled he won't ever be sent back to Iraq, where he was hit by sniper fire in 2005. The Wards are very patriotic, and they're proud of their son's sacrifice. But they say the repeated deployments have taken a big emotional toll on their close-knit family.
