One of the greatest warriors that had ever lived were probably the Burmese! They whoop the British arses with superior fire power several times before they could gain a foothold in Burma, and even then they always gave the British a very hard time and make them regret trying to subdue Burma. They were thinking of leaving Burma even before the Japanese took over. They thought they were more easy picking...large number of British and Indian soldiers were dying, I believe. But the greatest fighters that every live are probably the invincible Siamese fighters because he fought for his freedom, the country, the people and the king. He knows no fear...he is as cold as ice, and fighting is only his second nature.
