 The rehearsal concept allows us to build the team before we actually go ahead and execute the event. As an American service member, this exercise specifically ensures our interoperability with both our partners and our allies throughout the region. The importance of the rehearsal of concept is to identify friction points in our plan and synchronize the execution. I think this rock drill is a great example of how quickly you could bring together a team from across multiple countries, multiple services, and come together and execute a challenging event.
