“The Italian army in WWI also resorted to decimation as a disciplinary tactic.”
Reportedly (vs. purportedly), not exactly.
Six percent of Italian soldiers under his leadership faced a disciplinary charge during the war and 61 percent of them were found guilty. About 750 were executed, the highest number in any army in World War I. Claims have been made that he also reintroduced the ancient Roman practice of decimation—the killing of every tenth man—for units which failed to perform in battle. However, the military historian John Keegan records that his “judicial savagery” took the form of the summary executions of individual stragglers rather than the formalized winnowing of entire detachments.”
