Now, as they're backed tighter and tighter against the wall and know they're fighting a losing, suicidal battle, they can be expected to depart further and further from orthodox tactics, rely more and more on trickery. The first thing any soldier who is to fight against the Japs must learn is that under no circumstances are they to be trusted......
Very interesting pamphlet, great illustrations - published just days before the first atomic bomb was dropped on Japan.
