During the war, significant advances were made in military communications through increased use of radio, military intelligence through use of the radar, and in military medicine through use of penicillin, while in the air, the guided missile, jet aircraft, and helicopters were seen for the first time. Perhaps the most infamous of all military technologies was the creation of the atomic bomb, although the exact effects of its radiation were unknown until the early 1950s. Far greater use of military vehicles had finally eliminated the cavalry from the military force structure.
The Assembling Objects section of the ASVAB practice test measures your ability to determine how an object will look when its parts are put together. You will be shown an illustration of pieces and asked to choose which one, among a selection of finished diagrams, shows how they fit together. The CAT-ASVAB has 16 questions in 16 minutes, while the paper-and-pencil version has 25 questions in 15 minutes.

One set of ASVAB scores – Career Exploration Scores – tells you your current strengths in verbal, math, science, and technical skills.  The scores allow you to compare your test performance with that of other students at your grade level and can help you determine your readiness for further education and training in different career areas.  You will also receive a Military Entrance Score that is important for entry into the Armed Services.  You can discuss your score with a military recruiter.
Anyone who is planning to enlist in the United States Armed Forces should be familiar with the military’s standards and screening processes. An important part of this screening process is the Armed Forces Qualification Test (AFQT), which is a subsection of the Armed Services Vocational Aptitude Battery (ASVAB). This standardized assessment measures a candidate’s skills in the areas of paragraph comprehension, word knowledge, arithmetic reasoning, and mathematics knowledge.
The ASVAB test is taken by individuals interested in joining the U.S. military. It may be taken by high school students in the 10th, 11th or 12th grade. Or, it may be taken by someone who has earned a GED or higher degree. Along with determining your suitability for enlistment, the score you receive on this test lets officials know what military occupational specialties you may qualify for. 
You’ll find a great practice test and lots of other information about the ASVAB at the Department of Defense's ASVAB Career Exploration Program site (ASVABprogram.com). Since your test scores can have an impact on your Military Occupational Specialty (MOS)—and whether or not you can attend certain special schools (like Airborne school, Sniper school and many others)—we recommend you make the most of these additional resources.
