Welcome to the board from Southern California!!!
Thank you for your daughter's service. My daughter returned last September from a year in Iraq with the Army. Before that she spend a year in Afghanistan (glad she was there in that order!)
Any quilt that you make her would be loved. I sent one over to mine for each deployment and she really enjoyed having a touch of home in her "Hootch". You could just find some Red white and Blue fabrics and make something or find a pattern with stars in it.
I have a "Family Pride" quilt that I made during her first deployment that I plan on giving her when they get into their first home, (hopefully next month) (She married in June 08 and deployed in August the same year)
