Bureau of Alcohol, Tobacco, Firearms and Explosives Shutdown
You'll get your mail, but not your passports. Here's what's affected by the shutdown
National parks and gun permits
If you had plans for a vacation to visit any national parks, zoos or museums, some of those may be closed.
The popular panda cameras at the Smithsonian's National Zoo in Washington will be turned off, according to a statement from the Smithsonian Institution. Visitors will still be able to visit the National Zoo, as well as Smithsonian museums, over the weekend. But the zoo and the museums would be closed beginning Monday.
The shutdown will also affect the Bureau of Alcohol, Tobacco, Firearms and Explosives, meaning if you wanted a gun permit, you'll have to wait until the shutdown is over.
Military
The military is considered essential and will still report for duty. However, the troops -- including those in combat -- will potentially not be paid during a shutdown.
If the shutdown goes on for weeks, about 1.3 million active-duty military will be expected to work potentially without pay. The military is currently paid through February 1.
In addition, many civilian Department of Defense employees will not be working during the shutdown, including instructors at military academies and maintenance contractors.
