The Galactic Empire was at its prime after the end of the Clone Wars and prior to the Battle of Endor. The Battle of Jakku saw most of the Imperial Navy, Army & Stormtrooper Corps committed and wiped out.
I've seen only two mentions by an Imperial officer to "prepare for ground assault" so far: Agent Kallus to pursue Captain Rex and Darth Vader at the Battle of Hoth. Both times, the full deployment is just a handful of AT-ATs and whatever they can carry onboard.
From the rise of the Empire to before the Battle of Jakku, did the Empire conduct any large-scale ground assaults to the order of what is seen during the Clone Wars on any single planet - an actual war operation?
