One of the really notable things about war is that it’s so rare (if you aren’t the US military or else actively engaged in some ongoing conflict), and the rate of people dying and having to be replaced with brand new people is so high, that almost all the time it’s being done for real life-or-death stakes by people who are learning on the job as they go and have no real experience in what they are doing.
A lot of things about military decisions and events don’t completely make sense why they happened the way they do, until you imagine a whole airline being run by people most of whom it’s their first week on the job, and then you say oh okay I get it now; that’s why that happened that way.
