12 of the best photos of the US Marine Corps in 2016

2016 was a busy year for the US Marine Corps.

The service kept pretty active in training and in combat: Marine pilots have been, and continue to hammer ISIS fighters in Iraq and Syria, while Marine advisers operate on the ground in Iraq.

Meanwhile, the Corps started rotating troops to Australia and carried out other large training exercises around the world.

Here's what caught our eye.
