From the NKY Tribune, this is what they say it's for:

Gov. Andy Beshear said three Federal Emergency Management Agency (FEMA) strike teams he requested arrived in Kentucky Friday to assist the Commonwealth with record COVID-19 cases.

The teams will serve as backup for local ambulance services and perform patient transfers from one hospital to another.

“Our hospitals have never been more stressed and stretched during this pandemic than they are right now, and this FEMA assistance is critical to support some of our hospitals and health care heroes that need the most help,” said Gov. Beshear. “I will continue to act to boost our health care capacity and help our hospitals during the most dangerous stretch of this pandemic that has already killed more than 7,600 Kentuckians.”

With hospital staff and resources stretched thin, Gov. Beshear announced additional help the state has coordinated to assist hospitals, including: securing the FEMA strike teams; deploying the Kentucky National Guard to support COVID-19 response in hospitals; and providing COVID-19 testing assistance to some Kentucky hospitals.

The Beshear administration requested the FEMA strike teams from the National Medical Transport and Support Services to help with patient transports and patient care as the number of total COVID-19 cases, and cases requiring hospitalization, have dramatically increased in Kentucky over the past few weeks. At this time, the teams will not be responding to 911 calls, which are the responsibility of local emergency medical services (EMS).
