UPDATE: Transferring the forums to a new hosting company did not go well.
Not sure if this is the best place to post this, but I was poking around and couldn't find an explanation of the different designations in PFD. What is the difference between the engines, squads, and pipelines? Are the squirt and quint companies special units or do they function as crossover type companies, like St. Louis? Thanks in advance for any feedback.
