If anything, conscript militaries probably have higher average IQs than professional ones, because they get to employ almost everyone throughout society, giving them ample choice to select people into adequate roles.
Meanwhile, professional militaries only get to employ mainly the losers of society into grunt roles. The average professional soldier is basically the male equivalent of a female stripper or a whore.
