Knife Hands
You might be wondering what a knife hand is exactly. Well, it’s the hand someone makes when explaining a thing. The hand is flat and tight and all the fingers are aligned. Men and women, post-service, still use this when giving directions.

If a soldier says that they slept in, they probably mean that they slept until 7 am. The habit of waking up early which they get from basic training and deployment, somewhat sticks forever.
