Its a separate game and quite hard to find, basically it puts you in charge of a USFS (or something similar) firefighting operation. You get tank trucks, firemen, dozers, smokejumpers, helicopters and backburners. The game play is based around evacuating people occasionally and containing a wildfire as fast and cheaply as possible. Its interesting but gets old fast, EM4 could learn a thing or two from the wildfire physics though.

PM me if you want a more in depth opinion on it.
On topic would it be possible to have a firefighting helicopter as well as the air-tanker? Maybe have it use the same scripts as the air-tanker but have it extinguish less of the fire.
Many new scripts could be made that would make wildland firefighting more realistic in EM4 and its mods, however since most mods are based around urban areas (with a few exceptions) I doubt that a issue like that is at the forefront of very many of our modders' minds. Other things like pumper to pumper water transfer and all ATVs/UTVs have not been scripted for I suspect the same reason, lots of work for few mods to utilize. As someone who has a fondness for rural firefighting its a shame but that's not where the demand is.
