Park ranger
A park ranger, park warden, or forest ranger is a person entrusted with protecting and preserving parklands – national, state, provincial, or local parks. "Parks" may be broadly defined by some systems in this context, and include protected culturally or historically important built environments, and is not limited to the natural environment. Different countries use different names for the position. "Warden" is the favored term in Canada, Ireland, and the United Kingdom. Within the United States, the National Park Service refers to the position as a park ranger. The U.S. Forest Service refers to the position as a forest ranger. Other countries use the term "park warden" or "game warden" to describe this occupation. The profession includes a number of disciplines and specializations, and park rangers are often required to be proficient in more than one.
Ranger (character class)
While defensively limited, a Ranger does have some defensive boons including the capability to wear chain armour. Their armour class and hit points can be magically raised and they can cast a shield which harms their opponent when they strike the Ranger. In addition Rangers can reduce aggression and 'lull' creatures enough that they wouldn't attack when approached, giving enough distraction to pick groups of them off one by one. Along with the best tracking ability of any profession this means Rangers are often considered the masters of hunting, commonly taking responsibility for scouting ahead or choosing suitable 'prey' for a party.
