The Mandalorian did this with an AT-ST walker before (and also a TIE Fighter), but it’s nice to see this sort of thing again.
By the Force, Abrams is such a fucking hack.
Not every threat should be both over the top and background trivial just because Glup Shitto has a Midi-Chlorian count of over 9000. 
They never should have introduced droid/clone armies. Really ruined the drama and suspense of any battle. The Hoth battle is a desperate delaying action so people can escape but like when you can just clone up a whole army who cares if you lose a battle.
Eh…I disagree. If anything I feel like it just adds to the scrappiness/underdog status of the rebels. Every man and woman in the rebel alliance ( a few exceptions not withstanding) is a person who was convinced to join the cause. How can they compete with such a dominating totalizing force that can just grow more ground troops in a tank?
…where there’s a will and the force is on your side…there’s a way!
Edit: also if you want to get technical at that point it isnt just clone troops but I put that aside cause obviously that’s extended universe nitty gritty that’s secondary canon anyway.
