U.S. Army 101: The Complete Career Guide for Future Soldiers

It is 0430 on a Tuesday at Fort Moore, Georgia. A platoon of trainees stands in formation in the dark, breath visible in the November air. They have been awake for twenty minutes and they will not stop moving for sixteen hours. Somewhere in that formation is a kid from rural Ohio who could not afford college, a single mother from Atlanta who wants to be a combat medic, and a former high school quarterback from San Antonio who turned down a scholarship because he wanted something harder than football.

By the end of this day, one of them will qualify expert on the M4. Another will fail a land navigation course and have to repeat it at 0500 tomorrow. All of them will eat faster than they thought humanly possible and fall asleep before their heads hit the pillow.

This is the U.S. Army. It has been turning civilians into Soldiers since June 14, 1775 -- before the United States was even a nation. Today it remains the largest branch of the U.S. military with approximately 480,000 active-duty Soldiers, plus another 336,000 in the Army National Guard and 189,000 in the Army Reserve.

What Career Fields Does the Army Offer?

The Army organizes careers through Military Occupational Specialties (MOS) -- alphanumeric codes that identify every job in the force. During enlistment you will work with your recruiter and the results of your ASVAB score to select an MOS that matches your interests and qualifications. Here are some of the most popular and impactful MOS options:

Combat & Special Operations

• 11B -- Infantryman: The tip of the spear. Infantrymen close with and destroy enemy forces through fire and maneuver. ASVAB Combat (CO) line score of 87 required.
• 18-series -- Special Forces ("Green Berets"): Elite Soldiers trained in unconventional warfare, foreign internal defense, and direct action. Requires a rigorous selection process and exceptional physical and mental toughness.
• 12B -- Combat Engineer: Build, repair, and demolish structures and obstacles. Combat Engineers are essential in both offensive and defensive operations.

Medical

• 68W -- Combat Medic Specialist: One of the most respected roles in the military. 68Ws provide emergency medical treatment on and off the battlefield. Training translates directly to civilian EMT and paramedic certifications. ASVAB Skilled Technical (ST) score of 107 required.

Technology & Intelligence

• 25B -- Information Technology Specialist: Install, operate, and maintain the Army's IT networks. This MOS often leads to CompTIA Security+ and other civilian IT certifications.

What ASVAB Score Do You Need for the Army?

The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple-choice test that measures your aptitude across ten subject areas. Your overall score is expressed as an AFQT (Armed Forces Qualification Test) percentile.

• Minimum AFQT to enlist in the Army: 31
• Higher scores unlock more MOS options. A score of 50+ opens the majority of career fields.
• Individual MOS line scores (General Technical, Skilled Technical, Combat, etc.) determine eligibility for specific jobs.

Preparation resources are available at Today's Military and through your local recruiter.

What Is Army Basic Combat Training Like?

Army BCT is a 10-week program designed to turn civilians into Soldiers. Training takes place at one of three installations:

• Fort Jackson, South Carolina -- The largest BCT installation
• Fort Moore, Georgia -- Home of the Infantry and Armor
• Fort Leonard Wood, Missouri -- Home of the Engineers, Military Police, and CBRN

BCT is divided into three phases -- Red, White, and Blue -- progressing from basic discipline and fitness through weapons qualification, land navigation, tactical operations, and a final field training exercise. You will learn the Army Values (LDRSHIP): Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, and Personal Courage.

After BCT, most Soldiers move on to Advanced Individual Training (AIT) for their specific MOS, which can last anywhere from 4 weeks to over a year depending on the career field.

Can You Serve Part-Time in the Army?

Not everyone serves full-time, and the Army offers two part-time components:

• Army Reserve: Federal force; typically one weekend per month plus two weeks per year. Access to the same training, benefits, and retirement system.
• Army National Guard: Dual state-federal mission; serves both the governor and the president. Guard Soldiers respond to natural disasters, civil emergencies, and overseas deployments. Many states offer additional tuition benefits.

Both components are outstanding options for those who want to serve while continuing civilian careers or education.
