I'm looking for some help on how to change the helmet style on my firefighters. Currently my firefighters have traditional style helmets but I would like my guys to wear the salad bowl style lids. 

Sometimes the Firefighters do not change into or out of their SCBAs. What file is messed up or wrote wrong that I can go back and fix this?

How do you change the picture / icon on the left side of the screen or bottom of the screen of the selected units or persons. I changed the colors of the units and I would like the picture to reflect that. 

Looking for some info on how to mod a map. Nothing crazy just want to put an army base where there is a forest. I know how to get into editor and add and remove things. Just not  how to add roads and change the geography of the land.
