Whereas recruits who join as officers tend to be upwardly-mobile,[14][15] most enlisted personnel have a childhood background of relative socio-economic deprivation.[16][17][18] For example, after the US suspended conscription in 1973, "the military disproportionately attracted African American men, men from lower-status socioeconomic backgrounds, men who had been in nonacademic high school programs, and men whose high school grades tended to be low".[14]
The percentages of FY 1999 active duty NPS accessions in each AFQT category are shown in Table 2.8. The percentage of recruits in Categories I and II was approximately the same as their civilian counterparts (males - 39 versus 39 percent; females - 34 versus 33 percent). Category III accessions greatly exceeded civilian proportions (males - 61 versus 30 percent; females - 66 versus 37 percent), while the percentage of recruits in Category IV was much lower than in the civilian population (males - 1 percent versus 20 percent; females - less than 1 percent versus 22 percent). The low percentage of Category IV recruits is, in part, a result of DoD limits of 4 percent Category IV recruits, with even lower Service limits. Ten percent of civilian males and 9 percent of civilian females scored in Category V; DoD allows no Category V recruits.
Later this became known as military science, and later still, would adopt the scientific method approach to the conduct of military operations under the influence of the Industrial Revolution thinking. In his seminal book On War, the Prussian Major-General and leading expert on modern military strategy, Carl von Clausewitz defined military strategy as 'the employment of battles to gain the end of war'.[36] According to Clausewitz:

This advice, though well-intentioned, doesn’t address the needs of some new recruits who are interested in specific career fields but are worried about their test performance-especially in areas related to math comprehension. Potential recruits who feel deficient in math, language, or science skills should have a frank conversation with their recruiter to discuss possible refresher study or even supplemental classes in any self-perceived “problem areas” before taking the test.


As of 2017, the U.S. spends about US$610 billion annually to fund its military forces and Overseas Contingency Operations.[6] Put together, the U.S. constitutes roughly 40 percent of the world's military expenditures. The U.S. Armed Forces has significant capabilities in both defense and power projection due to its large budget, resulting in advanced and powerful technologies which enables a widespread deployment of the force around the world, including around 800 military bases outside the United States.[12] The U.S. Air Force is the world's largest air force, the U.S. Navy is the world's largest navy by tonnage, and the U.S. Navy and the U.S. Marine Corps combined are the world's second largest air arm. In terms of size, the U.S. Coast Guard is the world's 12th largest naval force.[13] [14][15]

Once you have learned about yourself, you are ready to begin exploring different career options.  Chances for a rewarding career are improved if you select a career field that matches your interests, values, skills, and abilities.  While learning about various careers, you should be constantly asking yourself, “How well does this career match my current interests, values, and abilities?” and “Will this career lead to a lifestyle I want?”

The Armed Services Vocational Aptitude Battery (ASVAB) is one of the most widely used multiple-aptitude test batteries in the world. It was originally designed to predict success in military occupations and is used today to help both those considering entering the military (mostly high school-aged students, but also anyone who is eligible to enlist) as well as those not interested in military service (who comprise the majority of current ASVAB test takers) what sort of career may be the best fit for them. Scores from the ASVAB can be used when enlisting in the military. Students interested in taking the ASVAB should check with their high school to find out when and if the ASVAB will be offered at their school. If it is not offered, students should meet with their guidance counselor to determine if it is possible to schedule a testing session in the future. There is no cost to take the ASVAB.
In the 1950s, the military adopted a single exam known as the Armed Forces Qualification Test (AFQT). Used as a screening tool, the AFQT measured a recruit’s ability to absorb military training and their future potential. It was supplemented by service-specific battery tests for the purposes of MOS classification. In 1972, the Department of Defense determined that all services should use one exam for screening and assigning individuals to an MOS. The AFQT was phased out over a two-year period in favor of the current Armed Services Vocational Aptitude Battery (ASVAB) test.
Every single individual that wishes to serve this country is without a doubt a brave person that deserves respect. These practice tests are offered because everyone wants to see these soldiers follow their dreams. Additionally, the nation as a whole firmly believe that those honorable individuals should not be held back because of their inability to recall some pieces of information. This nation does not just dream about making a difference.
I purchased your AFQT Secrets file, and I just wanted to let you know that I got a 99% on my test. I just got my job of choice today of Military Intelligence Analyst, and I am now on the road to my future career in the CIA or NSA. I just want to thank you again, and hope you have continued success in your ventures. Sincerely, Paul L. U.S. Army (Intel Analyst
The United States Armed Forces[8] are the military forces of the United States of America. It consists of the Army, Marine Corps, Navy, Air Force, and Coast Guard.[9] The President of the United States is the Commander-in-Chief of the U.S. Armed Forces and forms military policy with the U.S. Department of Defense (DoD) and U.S. Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All five armed services are among the seven uniformed services of the United States.[10]
Test scores provide only one measure of your skills and abilities.  Test scores and grades, combined with information about your interests, values, skills, and achievements may help you select appropriate occupations for career exploration.  As you explore careers, you can compare your skills with the skill requirements of occupations in which you are interested.
You can take the test as a junior or senior in high school and use the score to enlist, provided that you are at least 17 years old and took the test no earlier than 2 years before you begin enlistment processing. If you are at least 17, you can take the test at a Military Processing Station (MEP) or a satellite Military Entrance Test (MET) location.

Because most of the concepts and methods used by the military, and many of its systems are not found in commercial branches, much of the material is researched, designed, developed, and offered for inclusion in arsenals by military science organisations within the overall structure of the military. Military scientists are therefore found to interact with all Arms and Services of the armed forces, and at all levels of the military hierarchy of command.

Jump up ^ The United States Coast Guard has both military and law enforcement functions. Title 14 of the United States Code provides that "The Coast Guard as established 28 January 1915, shall be a military service and a branch of the armed forces of the United States at all times." Coast Guard units, or ships of its predecessor service, the Revenue Cutter Service, have seen combat in every war and armed conflict of the United States since 1790, including the Iraq War.

After adding so much information to the aptitude test, there was a bit of difficulty interpreting the test results. In addition to that, a vast majority of test takers were deemed as being under qualified based on their test results. This is why the percentile change was made. It ensured that a 50% actually correlated with a person doing better than 50% of the test takers. Those revisions have worked hand-in-hand with the preparation of the armed forces.
