Peacekeepers are soldier, police and civilian personnel. They are usually trained to keep peace in volatile states in line with rules of engagement. Peacekeepers risk their lives for the peoples of the far away countries where they are called to serve, and with which they often have very little in common, other than a shared sense of humanity. Since the beginning of peacekeeping operations an array of 71 missions has been established with 16 still ongoing. About 123 participating countries, 103,510 uniformed staff, 16,471 civilian personnel and 1,799 UN volunteers. Total fatalities recorded in all the peace operations since 1948 falls within 3,471.
