Military in Your Future?

It is not compulsory for a citizen of the United States to join the army. So, this means that I don't have to join the army when I grow up, but I do have the choice to. I wouldn't want to join the army, though. Even if it is for defending the country, I don't believe in violence and I could never stand to be a part of a war or know that I am responsible for killing or injuring a person. As for military training, I could do that. I just wouldn't want to be part of the actual fighting. I want to be a doctor when I grow up, so if I could be a doctor for any wounded soldiers, I would do that. I think that would be just as important as being out on the battle field because I would be helping in saving peoples lives. Also, there are many people joining the army, so it wouldn't really make a difference to me or the country if I didn't join. I'm not really brave and if it means risking my life, I would rather do something else to help my country.
