“Say Again”
You can also find out if someone spent any time in the military by the way they ask you for clarification. “Say again” is more commonly used among soldiers than “pardon me” and even “excuse me”.
Finding The Exits
Aside from looking out for things out of the ordinary, soldiers also make it a point to look for all possible points of exit the moment they arrive. This is just another military tic that will stay for the rest of their lives. In case of emergency, this will prove very useful.
