She was a reservist, meaning she was told she'd be training on weekends and working her regular job during the week. It should be illegal to send reservists to these wars of choice, but Dubya changed that during the War on Terror because no one wanted to go to Iraq and Afghanistan to die.
And I'm not comfortable blaming the soldiers just yet, when all the evidence we have is that the military and joint chiefs (sans Keg-Breath) told Donald not to do this and he told them to fuck themselves and did it anyway.
