"So we have to watch a video? Screw that."

I watched just portions of it. If there was any desire to convey information, that could have been done in ten minutes or less.

I have been officer of the deck on a landing ship tank. There could not be a more basic responsibilities than seeing your ship is always watertight and not overloaded.
