OCS? What is their training like? I cant swim, would i have a lot problems because of that? I still have an accent, would that make it hard for me? and what is life as an Army Office like? I am very excited of taking the exam to the officer exam, this is my last year of college. I am also very happy because I will finally become a US citizen, I have to many reasons to thank this country! Please answer sincerely. Thank you.
