Military signal tactics on show in Nanjing

Commandos from a PLA special forces unit in Nanjing, Jiangsu province, take part in a competition on Tuesday in the use of tactical sign language. More than 30 special police displayed the types of military hand signals used to improve battle tactics and skills. In close-quarters combat, or in terrorism operations, silence is necessary, so hand signals have been developed by combat forces to communicate with their comrades without being detected. [Photo/IC]
