I love the recent additions to the game. They have made it more fun and added more realism. We are still missing a couple of very key vehicles though.
First is is a Quint/Heavy Rescue and a Platform/Heavy Rescue. These are used by many departments across the country in place of or to supplement a Heavy Rescue.
Second is a combined Hazmat/Heavy Rescue. This may not be as common but many departments operate a combined special operations team.
Adding these units would allow for increased realism in game and I am surprised it has taken this long to add.
