You can join straight out of high school. Haaaa I remember when I stuck these 5 thumbs in your mother's asses puto.
You have to join first then get the opportunity to go ranger. You still have to go do your advanced individual training(job training) before becoming a ranger.
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.
