 I'm Major Matt Piosa, the CJTF J3 CHOPs. As the Combined Joint Task Force Chief Operations, my primary role in the rehearsal of concept is ensuring that we're executing a rock drill that allows us to identify friction points in our plan and then helps us synchronize the execution. The rehearsal of concept allows us to build the team before we actually go ahead and execute the event. This is my first time here to African Lion, and so far it's been great. As an American Service Member, this exercise specifically ensures our interoperability with both our partners and our allies throughout the region. I think this rock drill is a great example of how quickly you can bring together a team from across multiple countries, multiple services, and come together and execute a challenging event. The importance of the rehearsal of concept is to identify friction points in our plan and synchronize the execution.
