YouTube threw this story at me yesterday.

I don't know who won the Kilt v. Trews battle. It's likely it happened again as more amalgamation happened. My question really lies in an observation in the film.
Several years ago, I'd read a story about a WWII reenactor in England. He'd mentioned that he'd changed from British to American units because of the more "relaxed" marching style. My guess was he was addressing what I'd call arm swing or lack thereof in the American style.
I noticed that the HLI are not going as high as the YT videos of current units show. It's much lower and similar to an American style. I even remember a video about a British Army disciplinary barracks where the squaddie was reminded the get his armswing to shoulder height. Has the British style changed over the years or did the HLI have different regimental style? I know the Legion has a different style/pace from the rest of the French military.
