If your ASVAB score wasn't high enough to qualify you for the US Navy, then it's not high enough to qualify you for the US Marines either. Since you never swore in to the Navy DEP program, nothing ... besides not having a qualifying ASVAB ... will prevent you from being able to join the US Marine Corps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
