The Federal Aviation Administration, which worked on the ruling, estimates consumers and businesses will buy and fly at least 7 million drones by 2020.
A drone is flown for recreational purposes in the sky above Old Bethpage, New York on August 30, 2015.
In April, flights of almost all drones over 133 USA military facilities were banned due to security concerns.
Military bases are only one of many places where drones are forbidden; airports have the same restrictions, as does airspace over people and places where emergency crews are working.More news: Lawsuit alleges White House was complicit in Fox News conspiracy peddling
Earlier that year, a drone had landed on the lawn of the White House.
In recent weeks, the Islamic State militant group (ISIS) has used drones to attack U.S. Special Operations soldiers and disrupt airstrikes near the Syrian city of Raqqa, its remaining stronghold in the country, as well as to attack forces battling to oust it from Iraq. And now, civilians don't need to register their drones with the us government.
The Pentagon has sent new guidance to the armed services that lays out the military's authority to disable or shoot down any drone that violates airspace restrictions over a USA base and is deemed a security risk.
Details of this policy are classified, but Pentagon spokesman Navy Captain Jeff Davis said that it broadly deals with "rules of engagement" for bases when faced with civilian or commercial drones.More news: Inter try to end Man United's Ivan Perisic hopes
Attacks by drones aren't the only thing that has the military concerned about the devices, however.
The Pentagon said the new policy applies to 133 military facilities, presumably the same ones listed in April's announcement. Hackers have previously been able to breach the devices, altering security features. That announcement didn't say anything about the military reserving the right to obliterate or intercept drones, however.
The U.S. Army hasn't specifically stated how close a drone has to be before it gets shot down.
Prominent locations including the Pentagon and Washington are already "no drone zones".More news: Don't turn Hindustan into lynchistan, says Mallikarjun Kharge
