The first step is to contact an Air National Guard recruiter to find out if you are eligible. Initial screening will be conducted based on qualification criteria. Your recruiter will schedule you to take the Armed Services Vocational Aptitude Battery (ASVAB) test (if not taken in high school) and physical exam. Once "qualified" you will look at the possible list of career fields for you to choose from.
Gain and maintain active support from all public and private employers for the men and women of the National Guard and Reserve as defined by demonstrated employer commitment to employee military service.
