Quiet During Announcements
Soldiers show respect, so when they are receiving orders, they are quiet. Therefore, when an announcement comes on, such as at a baseball game or at the mall, you can expect to find soldiers standing quietly, at attention and listening.
Alternative Routes
Have you noticed that your military friend always looks as if they have several different routes mapped out when you go somewhere? Well, soldiers always have other routes planned in case disaster strikes. They never rely on just one route.
