 So, Mt. X is a cold weather training exercise that allows the Marines to not only just do our normal operations, but have the weather and the terrain factor in. 462 of me here, they've been really helpful, especially with our new guys who haven't done this before. This is actually a really great training to bring the bird asset because we're usually used to just hiking everywhere we go. We're out here supporting the ground Marines, inserting and extracting them into different LZs, and also training our aircrew on proficiency in cold weather training. As Marines, we're expeditionary by nature, so that means we fight and never be climbed in place. And it's important for us to get the training that we need and also help the Marines on the ground side to get the training they need to accomplish the missions in terrain such as this.
