 So, today Sierra Battery is, we're in the middle of Rolling Thunder, we're working with Second CB to create and refine expeditious trail operations in support of a high Mars battery in an EABO environment. So high Mars are going to have a great role in the future of the EABO environment. We work in high rains, which is a high Mars rapid infiltration. You load the launcher onto an aircraft of some sort, drop it potentially on an island. That launcher acts kind of alone and unafraid. They prosecute targets, they'll load back up onto that aircraft and return back. So that allows us to range targets in a deeper battle space. The overall objective of today's training is to better allow for survivability of high Mars in an environment where there's better targeting, UAS, things that make it more difficult for high Mars to hide. The engineers are greatly increasing the survivability of the high Mars, allowing us to create a trail system within the trees gives us a better ability to do reloads in the woods. Typically they're done out in the open, which makes it harder for us to hide. It allows us to create our own hide points that are going to better allow us to prosecute targets. Typically, we just pull into a GP or any sort of area and we have to use what's given to us. Sometimes there isn't even hide points, we just got to pull up a long tree line and utilize cami netting. So these engineers being out here with us allow us to shape our defensive posture better. So far in this location the engineers have given us an ammo hiding area, they've given us launcher hide points and they've given our fire direction center along with our platoon operation center better hiding spots in the tree line. So in a future battle space it's not just high Mars that are going to have to hide, cannons will also need to be hiding, the engineers can potentially take away some immediate crests that could take away some potential targets that cannons could execute. The integration of engineers into a high Mars or cannon platoon is greatly going to increase their survivability overall. Right now in Rolling Thunder for Sierra Battery and Second CEB it is a critical time period. It is allowing us to create and establish these TTPs and SOPs that are going to be critical in an expeditionary advanced base operations environment with the environment that we have around us, the vegetation is going to cause a large friction point for high Mars and artillery. So this is going to better allow us to operate in those environment, in that environment and execute targets deeper in the battle space.
