Also, when I said "hurry their asses off" there was no hyperbole.
Off the topic of the battles themselves for a moment and observing their commander for a moment: Zelenksy rarely, if ever, cracks a smile nowadays. He always has a grim and very stern expression, and his tone is one that is never jovial. He still cracks jokes now and then, but it's very dry sarcasm. Most of the time he's pretty pissed and curt even with his allies and benefactors.
