Just a little background on me. I am an active duty Marine (E5, so I do have some leadership experience), in pretty good shape and getting better every day, I have a 3.9 GPA, and I should be done with my Bachelor's degree early next year. To set myself apart from others I have taken the initiative in helping coordinate fundraisers for my unit's Marine Corps Ball fund, but I have not done anything in the way of volunteering. With that in mind, would it be necessary to get volunteer hours in order to be selected for something like SWO, Supply, or Aviation? I know that just about any question someone could ask on the topic of becoming an officer has been asked on here, but I cannot for the life of me find any information on this one.
