Great depiction of old navy vs new navy
I was in the military, active duty ~1970, and even then it was obvious who was who. The older folks that started during the very end of WWII or Korea, and the newer breed, college grads, or military academy. The former were often gruff, highly job focused, while the latter, both brighter and more educated, tended to be more empathetic, and split between the needs of the men and the job.
The older group, tended to achieve their status by not worrying about the needs of their jr officers. The ones in that generation that did, were passed over and left the service. It was fascinating to watch the 2 groups interact. Then 20-25 yrs later to see that dynamic depicted in a movie, brought back many of those memories. So if you are wondering if these types of battles really happened.....the answer is yes, they did. I can't say if they still do, but if I had to guess, I'd guess yes.
