As a layman I don't understand why the sequence in fighting fires seems to be
1- start with a skeleton crew of manpower and equipment
2-add crew and equipment after the fire is out of control
3-alerts and evacuations to follow
4-after a long protracted battle costing $, resources, and sometimes lives the fire is finally put out.
As a layman, and maybe I am wrong, it would seem to me a better approach would be
1- hit it early and hit it hard with all the manpower and equipment you have before it gets out of control, don't hold back the reserves until the situation gets worse.
That is just my take on firefighting, as a layman.
