It would be cool if the rangers and ACU teams could take damage. If the rangers would enter the carnivore enclosure, it would be likely that the rangers will catch the carnivore's attention and will attack the rangers and their jeeps would take damage. Now if the jeep takes too much damage, the rangers can abandon their jeep and try to run to the gate and escape, if they don't then the carnivore would eat them. If the rangers do escape, you have the option to airlift the jeep out of the enclosure then repair it costing less money but the jeep would sometimes break down, or airlift the jeep out of the enclosure and selling the jeep then buying a new one, but will cost more money. If you don't airlift the jeep out of the enclosure, that carnivore's infamy rises. Also the jeeps can take damage from storms, and be attacked by escaped dinosaurs.
Same with the ACU team. If the ACU helicopter gets to close to a large carnivore, then it will catch that carnivores attention and try to reach it and destroy the helicopter. If the large carnivore does manage to do so, then same thing that happened to the rangers will happen to th ACU team except that there is a chance that they won't survive the crash. Also like the rangers, the helicopters can take damage from storms but not dinosaurs because the copters are too high up.
