God bless your stepson and your family. He is a hero to set aside his life, family, friends, hobbies, and interests to go over there putting himself in harm's way so that the rest of us can stay here at home in relative comfort and safety. I know the significance of his service. Such generous people are true heros. May he return home safely. Fortunately, Iraq is a much less dangerous place than Afghanistan is these days.
My stepson, unfortunately, is now among the fallen heros. We lost him to an IED last December 5th in Afghanistan. We're in touch with his fellow brothers in arms over there on a daily basis through the internet and supporting them and their mission. We support your stepson and his courageous, heroic choice. Without fine young men and women like him, and our son, the rest of us would not be able to stay home enjoying this wonderful freedom to live our lives as we see fit.
God bless your stepson and keep him safe. Our thoughts and prayers are with your family.
P.S. Send a good knife and a good flashlight with him... he will certainly appreciate that.
