 Since the 2017 collisions, both the Surface War for Officer School and the Surface Force have made a number of significant changes to the way in which we train and assess officers. First and foremost, we've created a new course called the Junior Office of the Debt Course, which stood up in June of 2019 here in Newport, in San Diego, and in Norfolk. And in that course, we've more than doubled the amount of classroom instruction given to newly commissioned ensigns before they head to their ship. We've also increased the amount of time in simulation by more than tripling the amount of time of simulation that officers get before they go to their first assignments. When you flush it out in a simulator, you get to see a multitude of options. We get to go through it with the instructors and the students there discussing what other options might have been available to them in that particular scenario. How might you have done it differently? That ranges from high to medium traffic density contact management scenarios, ranges from things like anchoring or underway replenishment practice, all the way to things like extremist extraction, where we place officers in difficult situations. That ranges from high to medium traffic density contact management scenarios, ranges from things like anchoring or underway replenishment practice, all the way to things like extremist extraction, where we place officers in difficult and what would be in the real world dangerous situations in order to ensure that they know what to do or what not to do to keep their vessel safe when they're out at sea. Finally, in all of our courses across all of the continuum, we've added additional checkpoints and either competency checks or go-no-go assessments to ensure that every officer that precedes the fleet, whether they're a newly commissioned ensign or a major commander, does so with all the right skills and knowledge to be successful in their job. We're moving beyond just the text of the material and the theory of the material that we study in a classroom and moving it into more of a dynamic environment where we get to really get at practical application and understanding of the rules of the road.
