I was watching Fort Apache today (John Ford/John Wayne) and became very curious. I have noticed this before and just chalked it up to hollywoodism, but today, curiosity got the best of me.
At one point the troop is formed and the commander wants them to move off to the left in groups of 4. I think the command should have been thus; 1. Attention Regiment (company or squad), 2. By fours (twos or file), left, 3. march.
However, the word 'march' was replaced in the movie by the word 'hooo'. This occurs in many other movies (wagons hooo...) and the word is often strung out and may even be considered multisyllibiac.
I am curious if anyone knows the origin of the 'hooo' word.
