The English language gave the world the word "ranger" (sometimes render), which in translation has several meanings. Depending on the context, "ranger" means "wanderer", "vagabond", "forester", "hunter". But only after the nineties and acquaintance with Western cinema did it become clear that "ranger" is a very common concept.
English ranger
Rogers' Rangers are British military formations during the French and Indian War (1756-1763) that fought against the French and their Indian allies. These were detachments of light infantry, capable of moving quickly and delivering unexpected blows.
And in modern England, the rangers are called the counselors of the girl scouts. Those who collect garbage on the streets, sell cookies, volunteer in public events.
American ranger
1) The Texas Ranger is a public security officer in the state of Texas. This structure assists the police in catching criminals, rescuing people, searching for missing people and restoring public order. A kind of volunteer squad, which, however, has quite serious powers.
2) Power structures. Elite Light Infantry Regiment; specially trained loners in the special services, capable of carrying out assault and sabotage operations; in some places the mounted police are all rangers in America.
3) An employee of the state environmental service. That is, the very same foresters who "came" from England. They have many responsibilities and fairly broad powers, so you shouldn't quarrel with the American gamekeeper in his native forest.
Technics
"Rangers" and "Voyagers" in the United States are traditionally called devices for exploration of near and deep space. Basically, it is the name of a series of robotic lunar exploration stations. Also the proud name "Ranger" bears the model of the aircraft carrier, the brand of the sports bike and the cars of the "Ford" company.
Sports and surnames
Such a beautiful term could not be ignored by athletes. Today in the world there are many clubs named "Rangers" - Scottish and Chilean football clubs, American hockey and so on.
Ranger is also a fairly common surname in America, England, Canada, Australia. Famous - American artist Henry Ranger, Canadian hockey player Paul Ranger, controversial British footballer Niall Ranger and others.
Power Rangers
Perhaps, this word acquired the greatest fame precisely because of the fantastic TV series "Power Rangers", created by the Americans on the basis of the Japanese project "Super Sentai". Fighting good against evil, exciting adventures. Several ordinary teenagers who have received superpowers and super suits are saving the world - many generations of viewers are fans of this unique show, which Russia learned all the same in the nineties.
The meaning of the word "ranger" is very diverse. You can also mention a uranium deposit in Australia with that name; American revolver 32 caliber; the appearance of rangers in science fiction books and films as free shooters and hunters (including headhunters).
