What were elected every year by the roman assembly led the armies and served as judges?

I believe your are speaking of the Praetors (no exact translation except maybe First Men or primary officials, roughly) they should not be confused witht the Praetorian Guard who were a paramillitary police force somewhat akin to the German Waffen-SS and originally tasked primarily with bodyguarding praetors and other political officials.there was a phrase about the Praetors: Minima non Curat Praetor. Minimal or trivial matter does not concern legislators!) this was often the attitude towards, for example, U.F.O."s in the US, even by the Army and Air Force ( Blue Book) operatives- at one time Blue book was trusted to a mere sergeant! ( it had been headed by a Major for many years, but they lt UFO work lapse back to a Non-com role-maybe a side-hobby of a recruiting sergeant- as model airplanes often were! Oh we do get off the track.
