that is something that we're still trying to get the answer to here. but it's important that the united states maintains 10s of thousands of troops and equipment there in europe that could be moved around within the theater if necessary. the kinds of capabilities that we expect to get more detail on, that are on prepared to deploy orders that could be moved around within the theater are things like aviation support, logistics, medical capability and support and intelligence and surveillance. the ability to send over head assets to see what's going on, on the grund. we expect a large number of the 8500 troops are infantry soldiers. those are people who will be moved around ukraine. they're there as a potential deterrent from vladimir putin and a way to shore up and bolster defenses of some of the nato allies there. >> thank you.
