Cheating the Cycle of Life- A Padded Pony Collab

Flash Sentry recently became an enlisted soldier, after walking out of his barracks into some cold, late autumn weather. His instructions were to meet with one His Sergeant addressed Forward "March" Conditioning. every pony in  Flash's enlisting  batch had already went off to prepare  to that day's basic training before Flash, leading his sergeant to be pissed off.

"MAGGOT! since your slow as fuck I'm going to give you a special assignment after training. Get properly dressed for training then report to "the swamp" your bag is located in hall D, room 1A, is on row p, and the locker labeled 3r"

"D 1A p 3r got it?"

after following the instructions and the insertion of a key the locker opened. containing the uniform. "let's see, boots check, slacks check..." he shook the bag trying to get the rest of his clothing out. "shirt check and... jacket." upon neatly laying his clothes out on a seat he noticed a bulge within the jacket.

"strange, I have all my clothes out." he thought. He reached into one of the pockets and felt a note. "MAGGOT! due to your ineptitude and incompetence, you will be required to wear the garb inside of the jacket. Now hurry your ass up!"

"A..a...a.. diaper?" Flash looked at the back of the letter "you better wear the cloth diaper or I'll have you court-martialed!"

Flash reluctantly put the diaper and felt weighted down. Before any other soldier entered Flash quickly finished putting the exercise uniform on. With a sigh he walked outside ready to complete the march off to training at "the swamp"
