Just a clarification. The ASVAB is an aptitude test, not an IQ test. The Army doesn't conduct an IQ test as far as I know.
As for the rest of the topic, I've worked with soldiers that have had very high GT (General Technical = Sum of Word Knowledge and Paragraph Comprehension, scaled + Arithmetic Reasoning scores)scores that I would classify as book-smart or simply good test takers, but they were not intelligent. The only guy I ever met that had the highest GT score you can get was only good with paperwork, but couldn't conduct drill and ceremony or teach a class to save his life.
