I have a bit of concern with this call in particular...
It requires you to dispatch a fire truck, platform and battalion chief. In real life, only a single fire truck would attend the call so it makes me wonder why we need all 3 to attend it.
Most cities only have a handful of platform trucks, so having them travel for ages to a call that shouldn't require them is frustrating at times. When there are much more important calls such as large confirmed fires and you're waiting and waiting for a platform, you'll get my point...
In most if not all cases, one fire truck is sent to investigate. If there is something found, then THAT is when more get dispatched. I know for a fact that's how it works in Australia, and I'm nearly certain it's the same in the United States, and elsewhere.
So after saying all this... Could we have this mission modified so that it is more appropriately realistic? If for some reason not, then perhaps a separate call where you only require 1 fire truck?
