 So what this threshold blood transfusion allows us to do on the battlefield is it allows us to bring the mortality rate of a patient down significantly before they're able to be evacuated from the battlefield. This ultimately increases our lethality of the Navy and Marine Corps team. The history of the Valkyrie Fresh Hold Blood, it all originated from the Army Rangers ROLO program. When the Navy wanted to take that program and then introduce that to the Marine Corps, we turned that into the Valkyrie program in 2018. What we're trying to do now is implement that technique and teach it to our corpsmen so they could use it in the combat field and use it for their Marines.
