The National Fish and Game department.

You are looking for the US Fish and Wildlife Service for the wildlife part:

Park rangers would come under the National Parks Service:

Department of Natural Resources, National Park Service, USDA Forest Service.

game wardens now carry weapons.
park rangers also carry a pistol.
park rangers on fedral land. the white house
and any area that is a park or recration area.

You will find a list in your public libary.
you may find a list at the employment office.
you can write to a congras man and his office will
send you a list.

Bureau of land management. Forest service.

Join the Coast Guard.
They're "outside" all the time and they do major drug busts, rescues and all kinds of things.
They're the Fire, Police, and EMT service.
And, unlike a lot of other Federal Police Agencies they use machine guns.
Plus, you can retire after twenty years on the job with no age limit.

Federal Wildlife and Game have their own game warden, just like all the states does.
