Hands In Pockets
This one is almost the same as the previous about having one’s right hand ready. Soldiers tend to keep their hands out of their pockets, after all how can you react if your hands are stowed away? You’ll notice soldiers standing with their hands on their hips most of the time – a power stance.
Quiet During Announcements
Just like the close attention soldiers pay to the national anthem, mundane announcements get the same treatment. Soldiers are accustomed to taking orders and listening for developments, so even when they’re in the aisles of Walmart, when that announcement comes on, they’re ready to listen… and they want you to listen too.
