The military enlists people to fill the needs of the military. You won't know what you are qualified for unless you are tested by the ASVAB and take a physical. Up until then it's just guesswork and wishes.
Even the recruiter doesn't know what you are qualified for. He/she might know what's available, but won't commit until they see if you qualify. So, it's like a card game where they don't know your hand and you don't know their hand.
But since they are the "house", they make the rules.
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.
