US Army
The US Army performs a variety of missions and duties all over the world - and this year was no different.
They provided relief work to the victims of hurricanes in mainland US and Puerto Rico and artillery support as part of Operation Inherent Resolve. They suffered tragic losses in Niger and the Middle East, but also fulfilled a host of duties in calmer places in the world.
As 2017 comes to a close, we rounded up some of the best US Army photos taken this year that highlight these events and missions.
