Abstract
In the first part of the series of articles, we dealt with the theoretical foundations of cognitive intelligence, including primarily the possibilities of increasing military cognitive performance and the relationship between AI. Every military in the world uses some form of general cognitive intelligence assessment to place recruits in the right jobs. In the assessment, one form of examination is the examination of cognitive ability. The purpose of this article is to explore whether military cognitive intelligence assessments can actually work. Accordingly, in this second part, after the theoretical approach of the first part, we want to prove our hypothesis with practical examples, according to which cognitive intelligence can decisively influence the execution of tasks in armies, so it can be a decisive condition for successfully fighting a war.
