While that's not unheard of, it's not especially common. Firefighting, Rescue, EMS, and law enforcement are all specialized tasks, and some degree of cross-training makes sense (for instance, I'm a firefighter/paramedic, with some specialized rescue training), a 'one size fits all' approach where one person is trained to do everything often results in someone who does none of them well.
