"Military age male" refers to males who are of an age where they are eligible for military service. The specific age range varies by country and military branch. Here are some examples:

• In Algeria, the legal minimum age for voluntary military service for men and women is 18, and the mandatory service age for men is 19-30 years old.
• In the United States Army, the age range for enlisted soldiers is between 17-35 years old, while officers must accept their commission before age 31. However, the Army can lift some restrictions based on the need for certain roles to be filled. It’s possible to receive an age waiver if you retire with 20 years of military service by age 55.
• The age range for military service varies by country. As defined by the U.S. Central Intelligence Agency, "fit for military service" means all citizens of a country (both male and female) between the ages of 16 and 49 that are not otherwise disqualified for health reasons.

Its important to note that the term "military age male" has also been used in the context of drone strikes, where it refers to all boys and men over the age of 16, irrespective of whether or not they are actually participating in hostilities.
