When you join the Air National Guard, you don't just become a part of the world's greatest Air Force. You take advantage of a unique opportunity. The opportunity to enjoy the rewards and benefits of serving your country and community, while still having time to spend with your family, career, or school. After your initial Air National Guard training, you serve one weekend each month and two weeks every year, usually near your home. The rest of the time is yours to do whatever you like.
