Not to mention having never invented even the most rudimentary military tactics-- if you have a giant laser(ish) weapon, stay in orbit and use it! Don't send down your "artillery" into attack range of Earth fighter planes! Don't send snub fighters to be conveniently shot down and analyzed! Don't have a single central computer controlling your defense shields!

--But of course, if they did that, there'd be no way for the heroes to defeat them just in time.
