The Navy doesn't differentiate between wartime and peacetime for training or operations, generally. The difference would lie in what type of ordnance we used (real during wartime, inert during peace) and the measures we operated under at sea (we'd emit less signals and dog the hatches).
Also, in wartime, it's actually even more important that a new CO didn't upset the delicate balance or change procedures, because you need to rely on your skills and drills during wartime even more! Changing things just makes it harder to do your job and during wartime that would be deadly.
Also, you don't know where or when I served, so don't make assumptions.
