I am currently a Lieuey on a Paid-On-Call department.
Lemme see... Four Engines (three very active, one reserve), one ladder, three tankers (water tenders), one brush buggy, one attack truck, one rescue / medical truck, one squad car, and one ATV. I think that covers them all.
Our area is about 150 sq. miles and we get ~350 calls per year (medical and fire).
