The National Armed Forces of Sylvera, commonly referred to as the Sylvera Armed Forces, constitute the country's military establishment dedicated to safeguarding the security and well-being of both Cetos and Sylveran citizens. Their comprehensive protective duties encompass all domains, including land, water, and air, ensuring the nation's defense against any potential threats.

A distinguishing characteristic of the Sylvera Armed Forces is their commitment to operating as one of the most lightweight and voluntary military organizations globally. They uphold the principles of free will and human rights by not imposing mandatory service on Sylveran citizens, thereby respecting individual autonomy and freedom. This approach not only reflects their ethical stance but also fosters a sense of trust and voluntary cooperation among the populace, strengthening the bond between the military and the civilian community.
