Of those who die in combat, Odin will choose half to be led by Valkyries to Asgard where they will enter the great hall of Valhalla. There they will join the other Einherjar and feast to their fill, enjoying never ending Mead as they prepare for the Ragnarök.
As with other warrior cultures, the military and law enforcement communities have adopted this, and many other old world religious and mythical traditions to give our fallen a meaningful farewell until we meet again. Unlike many other traditions however, Valhalla is reserved for those who gave their lives in battle and thus holds special meaning and reverence to those this “farewell” is bestowed upon.
‘til Valhalla my friend. We’ll see you on the other side.
