Why did the US send troops that were not ready for combat in June?

In June 2021, the U.S. sent troops to Afghanistan primarily to support the evacuation of personnel and secure the embassy amid the rapid Taliban advance. These troops were not intended for combat operations but rather for protection and logistical support as the U.S. transitioned out of a two-decade-long military engagement. The decision was made as part of a broader strategy to manage the withdrawal while ensuring the safety of American citizens and allies.
