Speaking about such difficult theme like being a soldier I would like to say that we have to answer a question who is a soldier first. Is it a man fighting for his country, a man fighting for some truth or a person who serves the country without physical struggle?
On the one hand to be a soldier means to be a military man and serve the country and the people, to be ready for giving your life even if you haven't seen the beauty of it, haven't felt love and happiness.
On the other hand there must be some choice.
To sum it up I'd say-a soldier is a servant. Everybody serves. But somebody serves its country and somebody serves himself.
