A special unit of the Shanghai armed police's No. 9 contingent took part in a search drill on October 20, 2013. The paramilitary officers cross mountains, rivers and jungles; they climb cliffs, catch vipers and pick wild fruits during this tough field drill. They tackle anti-hijackings, ambushes and hostile encounters, as well as deal with the overall field survival and first-hand confrontations. [Photo/Xinhua]
