The Imperial Army is sourced from the worlds that constitute the Empire and their equipment and training vary wildly from one planet to the next. Some garrisons have equipment and training to rival that of the Stormtrooper legions, while others rely on munitions and tactics that would've been antiquated during the Clone Wars. The Empire has always placed greater importance on the use of mechanized units than the Republic, which during the lifetime of the Rebellion had trouble sourcing them in significant numbers and limited use for pitched battle engagements.
