The localization of Noreia which had influence on the ancient historiography has, until today, remained a matter of dispute stimulating the scientific discourse time and again. The author encouraged by his specific military qualifications ventures for the first time an attempt to tackle this problem from a completely different perspective, using a method, in general only military decision makers are familiar with, which is called the "Military Decision-making Process". At the beginning of his expositions, the author is referring to ancient deliverances with their scarce and ambivalent interpretable statements. The findings and thesis ? won by well-known scientists ? were hooked up and subjected to a critical judgement. Together they form the starting point for own localization approaches going beyond previous accesses, with their focal points, strategic, operative and military tactical considerations and furthermore human aspects. Trough out the decision making process it was mandatory to take the geographical, chronological conditions into account. Based on the succeeding situation assessment including two previous coordinated assessments and a special task development for the (virtual) target area, the author comes to the conclusion that the Noric settlement called Noreia mentioned by Appian, Strabon, Caesar as well as the elder Pliny must be located in the vicinity of both homonym road stations in the Tabula Peutingeriana, a 4th century (military?) road map. Eventually the author with his military decision making process comes to the conviction that the still nebulous and confused historic picture of the geographical-topographical situation of Noreia and also the ancient battlefield was brought closer to a solution. It remains undoubtedly the task of archaeological researchers to solve mystified Noreia with excavations in the field, without epigraphic credentials this might be unsuccessful.
