When I nerdpick a movie, I usually criticize the stupid computers, but I was fascinated by the angry nerding of Angry Staff Officer, a member of the Military Writers Guild, who picked apart the Rebellion’s outrageously dumb military tactics (some spoilers).
I was particularly amused to have it pointed out that AT-ATs have no side- or rear-armor or guns and that nevertheless, the Rebellion keeps on fighting them head-on.
By consistently refusing to learn the rules of unity of command, communication across the chain of command, and the necessity of preserving their force, the Resistance has fought itself nearly out of existence. If rebellions are built on hope, then they survive through skilled withdrawals—which almost never happens in the Star Wars saga. And in The Last Jedi, that failure has brought what was once a promising rebellion to the brink.
