My Marine friends were doing something similar in Fallujah, except it was Iraqi military police and soldiers. Other Marines were overseeing local and regional elections. Their time in the AO was about six to seven months. Army deployment time is expected to be cut from the one year or more it used to be.
3 months of her deployment with actually be stateside before she heads over, so I hope that means less time there. A mom always worries, but moreso with a daughter. I can only imagine what her mom feels. Her brother just came back after more than a year and now she will be going.
