The thread started with the simple question, "What are some of the most memorable things your drill instructors have said?"
We've collected some of the most interesting responses below. If you served in the military, feel free to add your own drill instructor line in the comments below.
One Marine was compared to a sugar cookie for being sweaty and covered in sand.
Another Marine was accused of being so bad, he had to be a plot to destroy the Corps.
Reddit user nickcorvus remembers how a drill instructor yelled:
"You're a communist plot to f--- up my Marine Corps."
At times, drill instructors could barely contain their rage.
... Or their disdain.
Some lines might not have had the intended effect.
In this case, a drill instructor had a more serious impact, when he handed this marine an Eagle Globe and Anchor (EGA) that signifies the end of new recruit training.
Ultimately, drill instructors always left their mark.
Even decades later.
