The WP article you link states that "Ruses of war are not prohibited", and https://en.wikipedia.org/wiki/Ruse_de_guerre https://en.wikipedia.org/wiki/Ruse_de_guerre includes this: disguising a warship to appear to be a neutral merchant vessel, or a merchant vessel on your opponent's side, has traditionally been considered a legitimate ruse de guerre, provided the belligerent raises their own flag to break the deception, prior to firing their guns. This was called sailing under false colors. Both sides during the world wars used this tactic, most famously the Royal Navy's Q ships. and also this: German commando Otto Skorzeny led his troops wearing American uniforms to infiltrate American lines in Operation Greif during the Battle of the Bulge. Skorzeny later reported that he was told by experts in military law that wearing American uniforms was a defensible ruse de guerre, provided his troops took off their American uniforms, and put on German uniforms, prior to firing their weapons. Skorzeny was acquitted by a United States military court in Dachau in 1947, after his defense counsel argued that the "wearing of American uniforms was a legitimate ruse of war for espionage and sabotage" as described by The New York Times.
