Diane Mahalco: My name is Diane Mahalco. I'm the medical section supervisor. The purpose of the medical examination is to make sure that the applicant is medically sound to enter into the Military. After they check in with processing, they're ushered down the hall to the medical session. They check in. We do their blood pressure. We do their vision test. We do a hearing test. Then they're sent over to the brief to complete all their paperwork, make sure their Privacy Act statements are signed, the HIV forms are signed. After that, they're given the commander's brief, the medical section brief, and then they're sent back over to medical, where they have their blood drawn for HIV, and then they give a urine specimen for a drug screen. After that, they see the doctor. Male and female exams are a little different, basically the same as if you were to go to your family practice. The female exam includes a pregnancy test. The females, you know, take a little longer. Then the males, basically, the males are all in one room, females one on one.

Speaker 2: What you'll be doing now is some orthoneurological maneuvers. It'll feel like we're testing your exercise ability, but we're really not. If anything that we ask that you do hurts or makes you feel lightheaded, short of breath, that sort of thing, take a break. It's not disqualifying to do so, and we certainly don't want you leaving here injured.

Diane Mahalco: If they are disqualified for a medical reason, the Services can opt to give a waiver for that disqualification, and that's usually the case. The duck walk, that's what everybody remembers, you know. The prior service people come in, and they always, you know, tell the applicants about the duck walk. My favorite part is seeing the applicants, when they're told they're qualified, you know, they're very happy. They're relieved, and you know, that just makes it all worth it.

Educational Requirements

Success in any branch of the Military depends on a good education. A high school diploma is most desirable. Candidates with a GED (General Education Development) certificate can enlist, but some Services may limit their opportunities. It is very difficult to be considered a serious candidate without either a high school diploma or an accepted alternative credential.

Security and Background Checks

For safety and security purposes, and to uphold the high standards of the Military, all Military Entrance Processing Station (MEPS) applicants are asked to complete a background check. Generally, felons or individuals with several convictions on their record are not eligible to join the Military. However, each branch has its own policy and, in certain cases, may grant moral conduct waivers or felony waivers:

Army
Felons and individuals with multiple convictions cannot join, but waivers are available on a case-by-case basis.

Marine Corps
All interested individuals must clear a criminal background check and have no felony convictions.

Navy
Individuals who have been convicted of a felony as an adult or juvenile for offenses involving violence, domestic violence, illegal drugs or sexual misconduct will be disqualified.

Air Force
A criminal record can impact enlistment eligibility (this includes an excessive number of traffic-related violations within a one-year period).

Coast Guard
The Recruiting Command can authorize case-by-case waivers.

If you have additional questions or would like further clarification, contact a recruiter to discuss your particular situation in more detail.

 

What to Expect From a MEPS Security Check

As part of the joining process, applicants will verify their identity and undergo a biometric scan and background check for health and security purposes.

Speaker 1: Good morning, everybody. I'm Sergeant First Class Ketcham. I'm the operations NCRC here at the Boston MEPS. I'm going to talk real quick about biometric enrollment. We did this this morning when you checked in, on your first visit at the MEPS.

Yeah, when they first arrive here at the MEPS, we do biometric enrollment on all the applicants. Basically, we're going to take their fingerprint. We use their primary finger, which is usually their right hand. And we'll also do a backup finger on their left hand. And then we're going to take a photo of them, which intakes 20 different points on their face. Once we get them into the database, all they have to do is show up at a station, get a copy of their fingerprint and, you know, that identifies them. And it's also a security measure because if somebody tries to come in and that's not the person, we use another finger that's going to tell us that as well. So it's going to keep all the applicants safe as well.

OK, once you're done with that, you need to come see the folks in processing, all right? You need to be open and honest with them when they sit you down there.

Speaker 2: You'll see during your visit here at the MEPS that the biometric process is the first step. We'll also be processing your fingerprints, disclosing any involvement you may have had with law enforcement.

They're going to ask you about 14 questions. They're going to ask you about speeding tickets, involvement with authorities. If you have any court cases open or closed, anything that you need to tell them, you need to make sure that that is documented. OK? Is that understood?

Speakers: Yes, sir.

Speaker 2: Committing to obeying the orders of the president and the orders of the officers that they fall under, and also their adherence to the Uniform Code of Military Justice. These are important concepts for them to understand, and that they will be held to a higher standard than people that they've gone to high school with.

Citizenship Requirements

U.S. citizens or Legal Permanent Residents (people who have valid alien registration form, I-551 or green card, from the US Immigration and Citizenship services). For more information on citizenship and naturalization, visit the USCIS website.

Properly documented noncitizens may enlist. However, opportunities may be limited. Contact a recruiter for more advice on a specific situation.

For enlistment purposes, the United States includes Guam, Puerto Rico, the U.S. Virgin Islands, the Northern Mariana Islands, American Samoa, the Federated States of Micronesia, the Marshall Islands and Palau.
