I've been in the Canadian army for about 8 years,I've been deployed 3 times twice to afghan and ones to hati for relief efforts.Now I don't want a life without the military even thow I wanna serve under the Canadian flag.But now that my discharge will be done soon and plus it's not really a option for me I want to do what makes me girlfriend happy so then it's off to housten grrrrrr!
