Just a big tip for everyone with the new update for the EMS Chief.
If you train 2 members in EMS Mobile Command and assign them both to the EMS Chief (this works for both fire stations AND rescue stations), the EMS Chief will auto-transport (via editing the EMS Chief vehicle) and it will count towards the EMS Mobile Command requirement on missions. Apparently not alot of people knew this, so incase you didn't, you do now :).
