 24% of the Earth's surface is covered by mountains. If you look at all of our operations and our conflicts that we've been in, there's always been arduous terrain at some point for operational sets. By using these animals and teaching this skill set, our students are able to learn something that they can take in where they could acquire it in country if needed be. They could use it for an evasion platform if they were compromised. Skills that we teach here off of our animals they can use anywhere in the world.
