The U.S. Armed Forces are one of the largest militaries in terms of the number of personnel. It draws its personnel from a large pool of paid volunteers. Although conscription has been used in the past in various times of both war and peace, it has not been used since 1972, but the Selective Service System retains the power to conscript males, and requires that all male citizens and residents residing in the U.S. between the ages of 18–25 register with the service.[11]
There are many misconceptions about what it’s like to serve in the U.S. military. If you don’t know any soldiers personally, you might think of the military as a place for infantry, trudging though rough terrain and loading giant artillery. Although that may have been true in the past, today’s military offers many opportunities that aren’t readily apparent to the typical high school graduate. For example, there are jobs in aviation mechanics, medicine, and accounting. There are also peacekeeping and humanitarian efforts by the United States military that require skills in verbal and written communication. Taking the exam can help you determine if you would be well-suited to one of these occupations.

In Medieval Europe, tales of knighthood and chivalry, the officer class of the period captured the popular imagination. Writers and poets like Taliesin, Chrétien de Troyes and Thomas Malory wrote tales of derring-do, featuring Arthur, Guinevere, Lancelot and Galahad.

Achieving the minimum required AFQT score established by an individual branch gets your foot in the door, but the higher you score, the better. For example, if you need a medical or criminal history waiver in order to enlist, the military personnel who make those decisions are more likely to take a chance on you if they think you’re a pretty smart cookie.
The Armed Forces Qualification Test (AFQT) is used by all of the Services to determine if an applicant is eligible for the military. Four of the ASVAB subtests are combined to form the AFQT.

The table below shows the AFQT categories and the percentile score ranges corresponding to the categories. Applicants that score in AFQT category IIIA or higher may qualify for enlistment incentives.
