During the construction of the main Joint Headquarters (JHQ) building, a Frankish battle ax (Francisca) was found. It was the badge NORTHAG chose because the Franks were a West-European tribe fighting against attackers from the East. In the year 451 AD the Franks defeated an army under the leadership of Attila at Châlons-sur-Marne and thus ended a conquest of Western Europe by the Huns.
