I know the officer who was Damage Control Assistant (DCA) on USS Fitzgerald (DDG 62) when she collided with MV ACX Crystal in 2017. She did an amazing job of minimizing the flooding and casualties sustained. Hardly a detriment to "Fighting Fitz." Of course, equal and opposite, I know of other personnel who happened to get pregnant just before deployment. Multiple times. In thanking someone for their service, you may be thanking a deadbeat or someone who has earned a rather prestigious medal. I also know people who wear medals because they play political games well and others who got screwed by those politics. The "fog of war" creeps beyond the battlefield.
