From the article:
The Japanese plan for dealing with tanks was simple. They formed Tokk? or ‘special attack' teams equipped with Molotov Cocktails and mines, relying on the superior moral fibre of the Japanese soldier to overcome matériel superiority.
The attacks by these men were known as Nikuhaku K?geki or ‘human bullet assaults' because the men's determination to destroy the tank transformed them into weapons.
