This weekend, the US and Australian militaries will wrap up a huge, biennial training exercise called Operation Talisman Sabre. It's been going on since July 4th, involving a fight between 30,000 Australian and US military personnel and a fictitious enemy. Lt. Gen. Stephen Lanza is the commander of the US Army's I Corps. In a phone interview from Australia, he tells In Depth guest host Jared Serbu that the exercise gave the military a chance to bring a whole-of-government approach to combat and stabilizaiton operations -- something he says the Australians happen to be particularly good at.
