An Air Force Reserve recruiter can answer your age related questions more thoroughly. Note: If you have previous military service; your adjusted age must be less than 40 years. To get your adjusted age, take your chronological age, subtract actual time of service credit, and the result is your adjusted age. For example, if you are 48, and you have 10 years of creditable service, your adjusted age is 38. In addition, the Air Force looks at your age and amount the total service time you have to make sure the individual can qualify for a 20 year retirement prior to age 60.
