A front line is a line of confrontation in an armed conflict, most often a war. On either side of the front line stand the forces of the various combatants. In modern warfare, due to the broken nature of mechanized combat, front lines rarely form; instead a zone of confrontation comprises a wide band where forces engage in battle.
Front Line is a weekly English radio program produced by China Radio International discussing about life in modern China. The flavor of the program is much like NPR's Morning Edition and All Things Considered. The program combines news, analysis, commentary, interviews, and special features, but from a Chinese perspective.
