SYDNEY Australia and the United States launched a massive war game on Monday aimed at honing their ability to act together against threats to Asia-Pacific security, commanders said.

More than 20,000 US troops and 12,000 Austra-lians, backed by a total of 30 ships and 125 aircraft, will be involved in “Operation Talisman Sabre 2007” on the northeast coast until July 2.

Vice-Admiral Doug Crowder, commander of the US Navy’s 7th Fleet, said uncertainty and unpredictability remained a threat to economic prosperity in the Asia-Pacific region.

“Therefore, it is very important that our militaries train together to carry out the types of missions our governments may call upon us to execute to ensure regional security and stability. “That’s exactly what Talisman Sabre 2007 is all about, further developing our ability to operate together as a combined military force,” Crowder told repo-rters aboard the USS Blue Ridge command ship in Sydney.

Australia’s Major-Gene-ral Richard Wilson said the operation was the country’s largest military training exercise. “Talisman Sabre is based on a fictional scenario that combines most of the difficult aspects of modern warfare operations,” he told reporters. The war game will involve parachute regiments and amphibious forces paving the way for land-based attacks, along with a series of land, sea and air exercises from bases at Rockhampton and Town-sville in Queensland state.
