A "civilian" refers to a person who is not a member of the military or armed forces. Civilians typically engage in everyday activities such as work, education, and community involvement. They play a crucial role in society by contributing to various sectors, including healthcare, education, and business. In times of conflict or war, civilians may be affected by military actions, often facing challenges such as displacement or loss of property. International laws, such as the Geneva Conventions, aim to protect civilians during armed conflicts, ensuring their rights and safety are upheld.
