Getting to the barracks late at night because you and your platoon were pulled in from the field due to thunderstorms. You change out of your ACUs into your PT uniform, and toss your ACUs into your wall locker. In the morning, you figure that you'll just roll with the change of ACUs that you have in your ruck sack already (as a part of the packing list), as you'll be wearing your PT uniform for the majority of the day until after you're done learning how to use zodiacs, making poncho rafts, etc.
Later that day, you change out of your PT uniform after learning all of the above, only to realize you left your name tape, your US Army tape (that goes on the left side of the uniform), your ROTC patch, and your US flag patch all back in your wall locker with your other uniform.
