 Our training today was conducting joint PR lanes with our AMSO Aviation Missions Fire Ability Officer and the British UK forces for their down-pilot recovery teams. So this type of training is important to get our interoperability with our allies, NATO forces, get us training with other forces because they use slightly different terminology and sometimes just keeps us ready to go as a combined NATO unit. To do joint personal recovery or as we call it combat SAR with the US Blackhawks is an ideal opportunity for us to do something a little bit different from our normal everyday run. So what we've been doing today is actually not only training our aircrew but also training our ground forces to be able to extract the aircrew using US helicopter assets. I think it's vital because quite often when we're going away on an operation you will deploy with a certain capability, we will deploy with a certain capability and if we duplicate that capability then we're wasting a lot of assets. So if you have a CSAR helicopter capability and we've got ground troops to commit use of that then it saves us bringing out our own helicopters or you bringing out your CSAR troops to conduct extractions.
