The Afghanistan pullout was an absolute disaster and regardless of Biden making the decision to pullout the way we did, those Generals should be ashamed of themselves. Beyond the Kabul airport bombing, do some reading on Task Force Pineapple or listen to some podcasts with some of the retired special forces guys who took part (Sean Ryan did an excellent podcast with the main guy who set it up).
Essentially the Afgan commando's around the country were abandoned basically overnight in the field on missions or not. All their support was pulled, their bases emptied of US personnel and equipment. By all accounts the commando's were excellent fighters and loyal US military groups they worked with. Their families began to be killed pretty much immediately and they were being threatened with death by the taliban. The retired special forces guys went back into Afghanistan and began to work with active special forces teams, marines, and others to begin pulling the commandos and their families to the airport to extract them. They were still actively getting personnel out of the country after our pullout. It's a total embarrassment to the US the way the clown of a president pulled out.
