Traditionally the native people of New Zealand (the Maori) used this 'dance' before battle to intimidate their enemies and prepare themselves physiologically for the coming conflict.
Here’s a great Haka

These days it is also often used when two iwi (tribes) meet peacefully in a formal situation and can also be used as a sign of respect.
i.e.
Cpl Willie Apiata (1-NZSAS) was greeted by a Haka when he returned home to his own Iwi after receiving the New Zealand Victoria Cross (similar to CMoH) for valor in Afghanistan.

(Watch from 3:01 onwards for greeting Haka)
Done well and preformed well it can truly be intimidating and IMHO is an excellent warrior tool. Most New Zealand military units have their own Haka's and it is 'performed' during base change-over & CO change-over ceremonies etc.
To my point…
I have some ‘Maori Ruanuku’ (Maori Elder) contacts from my Rugby days that a while back after hearing of my US Army aspirations offered to develop a simple Haka perhaps using the words from the US Army's "Soldier's Creed" or something similar.
This would all be unofficial of course but I would be interested on everyone’s thoughts on weather such a ‘tool’ would ever be used by a US Army unit. i.e. warrior performance at Infantry Basic graduation or similar events. Maybe it would catch on like the Unit Coin did?
I can just see each SF Company with it’s own Haka…ok…maybe not

, but still would be interested on weather anyone thinks I should take my Maori friends up on this offer and weather anyone would like to help with its development, word choices etc.
What would you think if you where in the crowd at an Infantry Basic Graduation and something like this were performed by 300 new soldiers? Obviously explained to the crowd first?
