You wanna see torture? Come back 5 minutes late from a 24 hour pass for doing well on a PT Test in Basic and have Drill Sargent Thornton waiting for you. I can still smell the hurl covering my chest as I ran, and did pushups, and ran, and did squat thrusts, and ran, and did situps and ran, and ran, and ran........ Well, you get the picture.
I’m going to guess you were NEVER late again for your DI.
