Join the Military
Most people join the military by enlisting in one of its branches. Enlisted members make up most of the military workforce. They receive training in a job specialty and do most of the hands-on work. Usually, you’ll sign up for four years of active duty and four years inactive. After you’ve completed your active duty time, you can either extend your contract or re-enlist if you want to continue serving.
Officers make up a much smaller part of the workforce. To join as an officer, you typically must have a four-year college degree and complete an officer program. Most officers are managers who plan and direct operations. Others are professionals like doctors and lawyers. Officers get paid more than enlisted members and enjoy certain other benefits.
You do not have to join as an officer to become one though. You can join as an enlisted member and attend officer training later on.
Steps for Joining the Military
Start by doing some research about your options for joining the military. Learn about the six active-duty branches and their part-time counterparts. Know the main differences between officers and enlisted members. And explore the career fields you can enter for each branch.
Once you know which branch you’re considering, contact a recruiter. A recruiter will give you an overview and answer your questions about that service. If you’re interested in more than one branch, contact a recruiter for each. If you’re interested in joining as an officer, the recruiter will explain any options you may be eligible for.
If you decide to enlist, you will report to a military entrance processing station (MEPS). You’ll spend a day or two completing pre-enlistment steps. These include taking the ASVAB, having a physical exam, meeting with a career counselor, and if you’re accepted, taking the oath of enlistment. From there you’ll receive orders for basic training, usually to start within a few weeks. If you enrolled in a delayed entry program, you’ll go home and get orders for basic training within a year.
