What term describes a member of the profession of arms who protects the value of life, often at great risk?

The term that describes a member of the profession of arms who protects the value of life, often at great risk, is "ethical warrior." This concept emphasizes not just the physical act of fighting or defending but also the moral and ethical responsibilities that come with being in the military profession. An ethical warrior is someone who understands the profound implications of their actions on human life and strives to uphold values such as honor, integrity, and respect for life, even in the face of danger. This connection to ethics signifies a commitment to preserving life and ensuring that decisions made in combat or during conflict respect the dignity of individuals.

In other terms presented, while "soldier," and "peacekeeper" certainly relate to members of the military, they don't inherently describe the moral dimension associated with the protection of life. A "soldier" typically refers to the role of a service member in combat, while "peacekeeper" describes someone who maintains peace, often in a post-conflict environment. "Defense leader" focuses more on leadership within a military context, but does not specifically address the ethical considerations in guarding the value of life. Therefore, "ethical warrior" best encapsulates the notion of safeguarding life at great risk and the intrinsic moral duty involved in that role.
