What is meant by the term "bear arms"?

The term "bear arms" refers specifically to the act of taking up or carrying military weapons. This phrase is often associated with the responsibility of defending a nation, which typically includes the idea of participating in military service, whether in combat or in other roles that require the use of firearms or weaponry. In the context of the N-400 application and U.S. civics, understanding this term is important because it relates to the obligations and rights of citizens, particularly concerning defense and military service.

The other choices address different aspects of military involvement or service but do not accurately capture the meaning of "bear arms." Serving in a noncombat role doesn't necessarily involve carrying weapons, while avoiding military service is the opposite of engaging in military duties. Engaging in peacekeeping missions might involve the use of arms but is more specialized and not directly aligned with the basic definition of "bearing arms."
