kind of surprised this isn't already in the game and no one has suggested it. both missions would need the forest POI. forest fire would require 7 fire engines, 2 water tankers, 1 command vehicle, 1 heavy rescue, 3 battalion chiefs, 3 police cars and the possibility of up to 5 casualties.
small forest fire would need 5 fire engines, 1 water tanker, 2 battalion chiefs, 3 police cars, a 40-60 chance of requiring a HRT and a 50-50 chance of requiring an MCV. it would also have the possibility of 5 casualties and the chance that the mission changes to Large forest fire.
