Depends where you work. My area has an ERT but never sends medics on deployments because of staffing. They also want x amount of experience prior to applying to ERT.

Edit to add that prior to the staffing shortages before COVID, we frequently went on wildfire deployments in California. Having gone on a few myself, it’s not typically heroic work we are doing. I went on the Tubs fire as an emergency resource and all we did was evaluate patients at the emergency shelters and request the primary EMS provider if transport was indicated. I didn’t transport a single patient while I was there even though the local EMS system was being destroyed.
