Emergency Services covers a very wide of operations. Ground missions include damage assessment, photography, search and rescue, mapping, crash site surveillance, UAS (drone) operations, Direction Finding (tracking ELT radio signals), Disaster Recovery, and others. Air Missions include everything from homeland defense to counter-drug to search and rescue and beyond. These missions need to be managed so the Incident Command System has its own set of skills.
Both cadets and senior members are involved in all aspects of Emergency Services but everything in Emergency Services has specific training that must be done and only proficient team members are deployed to an active mission. Cadets under 18 are restricted from some mission activities because of risk or legal liability but the vast majority of mission roles are available to cadets.
