China and Indonesia have launched their second joint military drills in Jinan, of east China's Shandong Province. The exercises between Chinese and Indonesian special forces will last 15 days.

The official theme for this year's military drill is "United to fight terrorism". It is bringing together Special Forces from the Chinese People's Liberation Army and Tentara National Indonesia. The teams worked on shooting, parachute landing, blockading and seizing tactics.

A combat-simulation system is also being used to mimic real-life situations and confrontation. This includes a specially-constructed street block of tens of thousands of tires.

Zhu Jianlong, Chinaese training team, said, "The tire houses have been built to mimic the structure of a city. Special forces teams can practice in-door tactical training in such a place without the worry of ricocheting bullets."

Meanwhile a parachuting ground has been built at a high altitude. It's a difficult landscape by choice - with obstacles like rocks and trees - to provide a chance to practice airborne landings in mountainous areas. A computerized warfare system will also be employed combining laser sensors and an automatic scoring system.

Ma Cunhong, PLA Jinan Military Area Command, said, "The screen can show a target, and prevent bullet ricochets. It ensures safety during shooting, as it is made of bullet-proof rubber. Tires and bullet-proof steel plates are also at its back."

Chinese Special Forces team comes from the Jinan Military Area Command of the Chinese Army. It has an 18-year history and has won awards in numerous international Special Forces competitions.
