Eh, it’s been old equipment and concripts for a bit now, but that’s not what the sent at first.
Trying to take a country using your C team and old hardware and then scaling up if things go badly is a radically bad strategy. It’s a great way to lose your C team, and then send more competent soldiers to fight against a prepared and well defensed enemy.
That might be what Russia did, but if so it’s a show of incompetence about in line with everything else we’ve seen and not some “better slow down” signal.
