Frequently Asked Questions
What is an MOS?
MOS stands for Military Occupational Specialty — the Army’s system for classifying jobs. Every soldier is assigned a primary MOS that defines their role, training pipeline, and career track. Enlisted MOS codes are typically three characters (e.g., 68W, 11B). Officer branch codes are two characters (e.g., IN, FA). Warrant officer codes are four characters (e.g., 151A, 255A).
How do ASVAB scores determine which MOS I qualify for?
The ASVAB produces a series of composite “line scores” (such as Skilled Technical, General Technical, and Electronics) calculated from specific subtests. Each MOS requires a minimum score on one or more of those composites. The Armed Forces Qualification Test (AFQT) score — derived from four ASVAB subtests — determines basic enlistment eligibility. See our ASVAB test prep guide for score breakdowns.
What is the difference between Active Duty, Army Reserve, and National Guard?
Active Duty soldiers serve full-time and receive full military pay, housing allowances, and benefits. Reserve soldiers serve part-time — typically one weekend per month and two weeks per year — and are eligible for retirement benefits and reduced healthcare options. National Guard soldiers serve their state as well as the federal government and follow a similar schedule to the Reserve. See our Active vs. Reserve comparison for a full breakdown.
What is the difference between an enlisted soldier, an officer, and a warrant officer?
Enlisted soldiers make up the majority of the Army workforce and perform operational roles. Officers are commissioned leaders who command units and manage operations. Warrant officers are technical specialists and subject matter experts who hold a unique rank between enlisted and commissioned officer. See our Enlisted vs. Officer guide for details on each path.
