Are You Eligible To Join The Military?

Are you eligible to join the United States military? If you are exploring your options for the first time, you might find the requirements a little confusing depending on what branch you wish to join, whether you want to enlist or join as an officer, or if you need to choose between active duty and the Guard or Reserve.

Some Basics About Joining The Military

There are some general rules that apply no matter where you wish to apply; Army, Navy, Air Force, Marine Corps, Space Force or Coast Guard. The first of these is the high school requirement. It is extremely rare for modern-day recruits to be accepted into the uniformed services without either a high school diploma (ideal) or a GED or other equivalency (not as ideal, but still workable with your recruiter’s help).

A high school student struggling to decide whether to complete high school or quit school and enlist will soon learn that such a concept is an old-fashioned holdover concept from the mid-20th century and is NOT an option today. For best results, finish your high school program before enlisting. Those who have dropped out should expect to be required to get a GED and possibly attend community college classes as a condition of enlistment.

Those who wish to become officers should know that there’s a basic, entry-level requirement for officer candidates–you need a Bachelor’s degree to be accepted as an officer. There is also additional training required, but this happens after you are accepted into an officer program.

In order to be considered eligible to join any branch of military service, the following should generally apply:

• You must be a U.S. citizen. The Army and Air Force official sites include statements that the applicant must be a citizen or a legal permanent resident with a valid Green Card.
• You must be at least 17 years old.
• You must have a high school diploma (see above).
• You must pass a physical.

The Process

You might think you are eligible to join the military and you may be correct. But some try to enlist or get commissioned without fully understanding what it takes to be approved to join. Standards will vary depending on the branch of military service you’re joining but in general you should expect a process with a variety of stages. For Army recruits (space prevents us from listing all processes for all branches) the road to becoming an enlisted soldier includes the following:

• Pass a background check
• Take the Armed Forces Vocational Aptitude Battery or ASVAB
• Pass an Army medical exam
• Meet with a recruiter to discuss career field options
• Take the Oath of Enlistment
• Depart for basic training

Those interested in becoming Army officers should expect a similar process. There are four different ways you can become an officer in the Army–attending college as a member of ROTC, get directly commissioned, attend Officer Candidate School, or attending a U.S. military academy. Generally speaking, all potential Army officers should expect some form of the following steps:

• Take a standardized test such as the ACT or SAT
• Pass an Army physical
• Talk to an Army representative
• Attend a commissioning program (see above)
• Graduate with a degree
• Pass the Army Basic Officer Leader Course
• Join your unit

In both cases, (officer and enlisted) applicants are required to have to pass a physical designed to screen out people who have medical issues that may make them unfit for military duty. Why?

Certain kinds of asthma and other health issues could be a barrier to entry depending on the nature and severity of the individual case. The military members and civilian doctors responsible for doing such screenings have sets of criteria that inform decisions to accept, deny, or request a waiver for a potential recruit with certain medical issues.

Are You Eligible To Join The Military?

What follows is basic information about joining the various branches of military service. Each service has different standards in certain areas and these rules are always subject to change because of mission requirements, legislation, changes in federal policy, executive orders, etc. Always discuss your needs with a recruiter; never assume the information you have now is current indefinitely.

Before discussing the various branches of service and their requirements, it’s good to know a few basics about things that can disqualify you from military service. Those who have certain legal entanglements, large amounts of personal debt, substance abuse issues, unresolved parental custody issues, or other complications will be required to resolve such problems prior to enlisting.

In fact, it’s best to delay your plans to apply to join the military until such problems are fully resolved as they can act as a barrier to entry. The Department of Defense won’t permit you to enlist unless these areas have been properly dealt with and there is documentation to support that.

Remember that there may be modified requirements for what’s listed below if you are trying to join as a Reservist or Guard member. You should discuss entry requirements with a Guard/Reserve recruiter especially if you are interested in joining the National Guard as standards may be under review or have recently been reviewed in light of changing missions, operation tempo, etc.
