As a soldier you can be compassionate. You can be loving and your gun can be helpful. There are times you may not have to use your gun. It is like that knife that is used to cut vegetables. You can be a bodhisattva as a soldier or the commander of an army. The question is whether you have understanding and compassion in your heart. That is the question.
