When I first saw his picture I thought, "Hey! It's the Dude from Wiki-leaks!" Separated at birth?
Anyhow, the Berserker-thing reminds me of other cultures with a similar class or style of fighting: In the Philippines it's called "running amok." Hmm... The "gang"
Berserkergang is like in German, run-way or door-way, entrance or exit, a "way" of some kind. Go through the doorway and come out the other side...berserk.
So there's various other cultures that promote a
Dionysian style (I like that) of crazy-mad frenzied combat and other words exist: Dionysiac, amok, anarchic, ecstatic, enraptured, feral, ferocious, fierce, frantic...
Origin: Portuguese amouco, from Malay
amok or Malay
amuk, "rushing in a frenzy" from of
mengamuk ("to behave amok, to be in an uncontrollable rage").. Early use was as a noun denoting a Malay in a homicidal frenzy - ultimately from Old Javanese.
The U.S. forces in the Philippines in 1900 ran into that, literally, among the Moros - the Muslim Malay peoples living in the southern Philippines where
the practice of "running juramentado" was a religious rite.
The word juramentado, meaning oath, was first employed by General Malcampo during the final occupation of Jolo in 1876. The practice of "running juramentado" was a religious rite involving the waging of a jihad, or Holy War, upon infidels. Originally, the practice was conducted by a band of men determined to sacrifice their lives in accomplishing the death of Christians. In the later years of the Spanish conquest, single individuals howled through the streets of Jolo, leaving death in their wake.
The jihad against unbelievers is enjoined in the Koran. In its pure form, the jihad consisted of bona-fide organized warfare against Christians. Juramentado was the degenerate form of jihad evolved by the Sulu Moros.
Which begs the question in Modern usage, where world Religions are promoted as paragons of tolerance and "Faith" (except for Christianity which continues to be media-characterized by the Spanish Inquisition while the pacific teachings of Jesus are ignored), what the hell kind of
Religion is it that has specific tenants related to the practice of killing others in
warfare?? Oh yeh, this kind:
In the deep silence of early morning, fanatical youths gathered to hear the Imams, or priests, tell of the old days. The stories flamed these ambitious recruits to martyrdom, and custom then necessitated a solemn conference with their parents. After a family council, which usually granted permission for the youth to run juramentado, the youths were banded together with the Sultan's permission to engage in a holy war.
The candidates were then turned over to the Imam for organization and instruction. Prayers were offered and each candidate placed his hand upon the Koran and repeated the following: "Jumanji kami hatunan ing kami ini magsabil karna sing tuhan." (We covenant with God that we will wage this holy war, for it is of God.)
Also we see that this method of frenzy-attack wasn't brought about by any particular act of the later arriving Americans, but was initiated by the Moros specifically as a part of their tactical doctrine. It's simply how they operate.
We held our John C. Garand Match yesterday and the weather was beautiful, but turnout was a bit light. A bunch of the talent against whom we traditionally compete was back East somewhere there's some kind of big Match taking place, so good for them and their Youth Program.
