My usual response guideline is at least a single ladder truck and a rescue truck. Different mods change my dispatch however. in the new manhattan (3.0) I dispatch 2 trucks and the rescue. LA, usually a truck, engine, and USAR, Harbor City barely has that event but I do a ladder and rescue or squad. NYC 1.01 is ladder and a Rescue. Gotta make different dispatching guidelines dependent and mod and be ready for any situation by knowing what to send having backup plans.
