Wow! Just got chills! As a former Sailor I'm so happy to hear that the Navy is FINALLY trying to communicate with millennials! For so long it seemed like Big Navy thought they could remove the millennial way of thinking, like just beat it out of us, not realizing that millennials are our future! Any military force that doesn't recognize that and get onboard quick will be left in the wake.
Separately having worked in the Intelligence community I highly recommend that Sailors do not share their social media usernames with the government or anyone else for that matter. Do not have a username that directly ties to your identity in anyway. Just a recommendation. I'm not going to elaborate on that subject any further.
