In this Dec. 29, 2010 photo, an Israeli soldier handles explosives during an army drill near the Shivta Field Artillery School, southern Israel. Israel is among several nations to harness digital and satellite technology to develop "C4I" systems _ short for "command, control, communications, computers and intelligence." The latest version of the communication system that compiles battlefield information in an easy-to-use, video game-like interface, allows all forces on the ground to communicate instantaneously.(AP Photos/Bernat Armangue)
