For example:
* United States: The primary test used is the Armed Services Vocational Aptitude Battery (ASVAB). This test yields several subtest scores that are combined to create composite scores, which are then used to determine eligibility for different military occupational specialties (MOS). These scores don't directly translate to a single "aptitude score" number but rather indicate strengths and weaknesses in various areas (e.g., verbal, math, spatial reasoning).
* Other Countries: Other countries will have their own equivalent tests, with varying names and scoring systems. These tests assess similar aptitudes, but the specifics of the test and interpretation differ.
In short, there's no single answer to "what is the military aptitude score?" It's a broad concept referring to the results of various tests designed to gauge a recruit's suitability for military service and specific roles within the military. The specific test and interpretation depend entirely on the country and branch of service involved.
