I don't know a lot about them, except that they are Phoenix engines that are manned by "red shirt" recruits (probably with a career Captain and Engineer) who "jump" calls around the city in order to get real life experience. Glendale does the same thing with their two medic units who are staffed by Glendale Fire and Southwest ambulance paramedics and paramedic students from one of the local universities.
