Ruse de guerre

The French ruse de guerre, sometimes literally translated as ruse of war, is a non-uniform term; generally what is understood by 'ruse of war' can be separated into two groups: the first classifies the phrase purely as an act of military deception against one's opponent; the second emphasizes acts against one's opponent by creative, clever, unorthodox means, sometimes involving force multipliers or superior knowledge. The term stratagem, from Ancient Greek strategema (στρατήγημα, "act of generalship") is also used in this sense.
