SIXIEME COLONNE

The book's depiction of tactics and leadership feels quite detailed and ahead of its time. I'm curious whether Heinlein's experiences shaped these scenes or if they were purely imaginative.

The characters often walk a fine line between right and wrong, which made me wonder how much of that complexity Heinlein intended to explore or challenge readers with.

Understanding Heinlein’s background during the era he wrote this could shed light on the story’s emphasis on unity and defense, especially given its historical context.
