US and Filipino troops fired missiles and artillery at an imaginary "invasion" force during war games on the Philippines' northern coast on May 6. About 200 soldiers took turns defending the shores of the coastal city of Laoag launching Javelin missiles, and firing howitzers and machine guns to repel their “enemy.” The annual drills, dubbed Balikatan, involved about 16,000 Filipino and American troops. The drill comes days after the Filipino government objected to China's "dangerous" actions in regional waters amid heightened tensions. Watch the video to find out more.
