The powerful image, tweeted Thursday morning by the Florida National Guard, is going viral after its message hit home: "When everyone else is headed out, your Florida National Guard is headed in," the tweet said.

People tweeted in response to the National Guard, thanking them for their work. As of Friday morning, the photo had been retweeted more than 1,000 times.
