 Today, we are taking all of our folks in First Brigade who are type O blood and we are titering them for antibodies. One of the issues that we've had throughout the last 20 years of conflict was how to bring fresh whole blood as far forward as possible. What we've learned is that when you're resuscitating a trauma patient, the best fluid to replace blood with is blood. Cold stored blood products have to be refrigerated. They only last for so long. So what we're doing here today is we're essentially turning all of our O type blood groups here in First Brigade into donors at the point of injury. So for example, if there's a platoon outmaneuvering and they take contact, someone needs whole blood. What we're doing here is allowing the medic at the point of injury to pull a unit of blood off somebody and give it directly to the patient at the point of injury. Why this is so interesting is because this is a capability that soft elements have had for a long time. And this is the first time that we're going to see the Army start implementing this at scale.
