While watching the parade, I wondered
Are these guys active duty, with an MOS that, literally, involves "shoveling horsesh!t"?
BTW the Marine Band looked pretty sharp, did not see any USAF types tho.
The stable orderlies shoveled the sh!t. Not that it's that bad a job. Horses eat only grass, hay, and grain - so it isn't like you're shoveling the output of a carnivore. I've probably shoveled 30-40 metric tons of the stuff over the last 45 years or so.
Just the price you pay for getting to play with horses.
