This exercise is a major undertaking that reflects the closeness of our alliance and the strength of the ongoing military-military relationship.
Talisman Sabre 2011 is a U.S.-led, Australian-supported exercise to improve combat training, readiness and interoperability, across the spectrum of military operations from conventional conflict to peacekeeping and humanitarian assistance efforts. The exercise forms part of the Australia Defence Force's extensive training program to ensure the ADF is prepared to protect and support Australia and its national interests. The exercise also contributes to the ability of Australian and U.S. military forces to work together efficiently and safely. By working with the U.S. military forces, the exercise strengthens proactive and responsive strategies and enhances measures to defend Australia and its national interests.
