The Chinese People's Liberation Army (PLA) started its largest-ever military exercise on August 12.
Experts say the exercise has already revealed new trends in the country's military development.
Motorized troops from the military command of Lanzhou pass a bridge on Tuesday. The exercise "Stride-2009" participated by one army division from each of the military commands of Shenyang, Lanzhou, Jinan and Guangzhou started on Tuesday, August 11, 2009.
It is the first time the PLA has mobilized four full divisions amounting to about 50,000 troops and deployed 60,000 pieces of heavy equipment up to a maximum of 2,400 kilometers from their bases, accompanied by army aviation units.
To test the mobility of the world's biggest army, numbering nearly 2.3 million - which has not been engaged in a major military conflict for nearly 30 years - PLA headquarters selected four elite divisions from its Lanzhou, Shenyang, Jinan and Guangzhou Military Commands to carry out the two-month long exercise.
The PLA's General Staff Headquarters said three of the divisions had glorious battle histories stemming from victories in the Sino-Japanese War (1937-1945) and victories against US troops during the Korean War (1950-1953).
"They are required to improve PLA battle effectiveness in a modern warfare environment for the present and in the future," Gong Fangbin, a professor at the PLA's National Defense University, said Wednesday.
"Long-distance mobility is a key requirement for the armed forces to carry out anti-terror missions and operations to protect China's overseas interests," Gong said. The professor said the exercise also revealed a transformation of the country's defense construction concept.
"China is less likely to face a large scale inland attack since no other countries - including the United States - want to take the chance of adopting military force in dealing with Chinese affairs.
"Instead, China is now in growing demand of smaller, agile task forces able to conduct precise joint operations," he said.
