 The military nature of the Mycenaean Greeks is evident by the numerous weapons unearthed , warrior and combat representations in contemporary art , as well as by the preserved Greek Linear B records . The Mycenaeans invested in the development of military infrastructure , with military production and logistics being supervised directly from the palatial centers . According to the Linear B records in the palace of Pylos , every rural community ( the damos ) was obliged to supply a certain number of men who had to serve in the army . Similar service was also performed by the aristocracy .
