[Star Wars]How good of a military leader was Darth Vader?

What were his tactics? How was he strategically? The rebels were able to elude him for quite some time.

His tactics and stratagem were a lot like they were when he was Anakin, just much more direct and brutal. He *could* be as creative as he used to be, but after Mustafar he definitely developed a “just get it over with” mentality to combat, preferring overwhelming force to complex tactics.

He was pretty good at it (in direct battles with Rebels he demolished them nearly every time; the Rebels kept alive in the early days of the war by *evading* him and trying to avoid fighting unless necessary) but everyone has their off-days and his methods tended to leave little in the way of salvage; if the Empire wanted someone alive or to use the resources of a conquered location, Vader wasn’t usually the first choice outside of extraordinary situations like the fiasco with the Death Star plans or hunting Jedi that were too strong for the Inquisitors to handle. 

The Battle of Hoth really gives a good idea of what Vader was like as a wartime leader; he did everything he could to arrange a perfect ambush, but when an overzealous admiral fucks it up by dropping out of hyperspace too close to the system, Vader just rolls with (after killing the guy of course) and proceeds to launch a full-scale assault that is so effective the Rebels only barely make it off-planet and still take major casualties. 

So yeah I’d say he was a quite good tactician/strategist, if not *as* good as he was during the Clone Wars.
