 So, this is training area metting, what we're doing here is we are training with the German medical unit, they're doing the equivalent of the expert field medical badge training, which is a badge they get for being tactically and technically proficient as a German medic, so we're giving them scenarios such as nine lines in order for them to attain this badge. So, cold load training is when we teach ground forces how to approach the aircraft safely, from which way we want them to enter and exit the helicopter at all times, make sure that they're safe, make sure everyone in the aircraft is safe. Hot load training is the same concept as that, except the main road of blades are turning, the engines are on, it's loud, and Wendy and a lot more is going on around the aircraft. This is fantastic for all of our soldiers, we don't get to do training like this especially back in the states with our allies, so getting out here and learning the different standard operating procedures for our allies such as the German medics here is unparalleled in the training. I've had quite a few opportunities to work with them throughout my career and I've always thoroughly enjoyed working with the German Bundeswehr, German military, they're very hospitable and very kind individuals and they always make training a good time. Yeah, no this is great for us, this is what we're here in Germany for is to assure our partners deter and build readiness. So this is fantastic, it's great to be out here with our German allies, building readiness for both our mission and also helping them attain some of their goals like this medical battalions method.
