Whomever America chooses in 2016, among his or her first orders of business will be to spend a lot of time getting briefed on where the U.S. military is deployed.
Service members around the world are currently conducting airstrikes, raids, bilateral training missions, and other operations to help America and our allies. These six ongoing conflicts will certainly still be on the plate when the next president gets up to bat:
1. Iraq and Syria

Few people need a primer on what is going on in Iraq and Syria. ISIS holds territory and is murdering thousands of people. America's involvement against ISIS has been slowly growing.
We've lost three service members there. Army Master Sgt. Joshua Wheeler was killed while rescuing potential victims of an imminent massacre, Marine Staff Sgt. Louis F. Cardin was killed in a rocket attack while providing fire support for coalition fighters, and Navy SEAL Charles Keating was killed while rescuing other American advisors caught by an ISIS surprise attack.
While the Obama administration has tried to keep America's footprint on the ground relatively small, 300 troops in Syria and approximately 4,000 in Iraq, the Navy and Air Force have been busy conducting air strikes to support both American and coalition ground forces.

Of course, ISIS operations aren't limited to Iraq and Syria. Portions of Libya's coastal areas are controlled by the terror organization. A few dozen U.S. troops, most likely Special Forces soldiers or other operators, are deployed there to help the competing national governments fight further ISIS attacks.
America has launched airstrikes there in the past to topple ISIS leaders, but that was put on hold. According to Marine Corps Lt. Gen. Thomas D. Waldhauser, the current nominee to take over Africa Command, no more troops are currently needed in Libya but more airstrikes would be beneficial.

While the U.S. officially ended combat operations in Afghanistan in 2014, approximately 9,800 troops are still deployed there. It's an "advise and train" mission, but reports have surfaced of operators engaging in direct combat.
The Taliban is still the greatest threat in Afghanistan and most coalition missions are aimed at them. ISIS has captured ground in the east of the country, though. America flies drone missions to kill local ISIS leaders while militias provide some muscle on the ground.
4. Horn of Africa

In addition to working against ISIS in Libya, American troops supporting African forces have been engaged by Al-Shabab terrorists in Somalia and Boko Haram in Cameroon. U.S. troops have previously helped hunt Boko Haram fighters and hostages in Nigeria.
These missions are expected to continue for at least the next few years as both terror organizations have proven resilient.
5. Eastern Ukraine

American troops aren't deployed to eastern Ukraine where government troops fight Russian-backed separatists. But, the U.S. has provided training and equipment for government forces while Russia has provided materiel and troops to the separatists.
A fragile cease-fire from late 2015 has reduced, but not eliminated, fighting in the Donbass region and both sides are violating the cease-fire. Ukraine has failed to remove heavy guns and other equipment and Russia has deployed more fighters and equipment to the area. There's no sign that this conflict will be done when the next president takes office and most signs point to it actually being worse.
6. South China Sea

The conflict in the South China Sea is currently bloodless but has the potential to become the biggest fight on this list. Multiple nations claim territorial rights in the South China Sea, an area that controls a huge amount of sea traffic and is estimated to have large oil and natural gas reserves.
China has built islands that it may or may not hold sovereignty over and is conducting military drills in the area. Meanwhile, American Navy ships and planes are conducting freedom of navigation exercises there, sailing through contested water and flying over contested islands as a way of disputing Chinese claims.
China has conducted dangerous intercepts of these flights and is becoming more aggressive as a United Nations ruling on certain areas of the South China Sea looms. If the conflict gets more aggressive, the world's two largest navies could end up in combat against one another.
