Five pillars defend America: Army, Navy, Air Force, Marines, and Coast Guard. On land, sea, and in the air, these forces safeguard our nation. The Army’s boots hit the ground. Naval ships patrol vast oceans. Air Force jets soar overhead. Marines adapt to any battlefield. Coasties secure our shores and save lives. Though diverse in mission, these branches unite under one flag. Together, they form an impenetrable shield, protecting American interests at home and abroad. Their shared goal: to serve and defend, no matter the cost.
