As part of the immensely popular "Real Heroes" series, the 4th issue pays tribute to the world's lifeguards, especially those serving in the United States Coast Guard. As one of six military services, its members have fulfilled their unique duty as a humanitarian and security force protecting America in domestic and international waters for over 100 years. Although involved in all aspects of U.S. law enforcement and commerce on the high seas, the U.S. Coast Guard is a unique security force best known for its daring search and rescue operations, including medical evacuations, downed aviators, foundering vessels, floods, and hurricanes. Even today, these real heroes save countless lives in need, true to their motto "So others may live."
