  In cases where the test misfired, you would had higher IQ people recruited into canon fodder positions where they chance of dying is higher then normal. Army aptitude tests do not test IQ directly. They test general knowledge (like basic math), ability to follow directions, that sort of thing. IQ is not the only mental issue that makes you unsuitable. So kinda, reliability of those tests is not really relevant.

  The article goes to lengths to explain that the aptitude tests for these draftees were regularly faked. The point was that people who were manifestly mentally unsuited for the military (whether because of a physical disability or lack of education due to poverty, etc.) were intentionally drafted; nobody is required to have a particular opinion on IQ to think that was probably a bad idea.
