It'll be fine - they have to go to work and do a job just like you and I do. No military bases have been shutdown, everyone is taking precautions at work, but the key thing to understand is that people in the military are still going to work to do their jobs. This may become more of an issue if there is a national quarantine, but until that happens there is no need to freak out. Just carry on with your day and stop stressing.
