 Right now we're doing the obstacle in placement and engagement area development for a company defense as part of a larger division leaders professional development on engagement area defense. The fun part of being an engineer is you get to kind of use some of your creativity a little bit and thankfully there's so much historical indoctrinal resources that you can use so there's pretty deep tool belt to reach into. So we were kind of figuring out what we wanted to do with this area here. Without just leaving it open we wanted to kind of fix the enemy here so that our maneuver counterparts can kill them in this engagement area. So I was looking through the engineer field data manual and came across log hurdles and they're great. They have a they have a low obstacle profile. So it's difficult to see from a tank as you're you know moving forward and you're being fired upon by the by the infantry and the intent behind it is that basically the tanks will hit it and hopefully they'll hit two successively and we hope to dislodge their tracks and hopefully disable them right here kind of in the middle of their main avenue approach. So obviously with engineers you got three main areas of focus especially in a brigade combat team and that's mobility counter-mobility and survivability. Mobility is the one everyone thinks of because they always see the explosions and they look super awesome. But a huge part of that especially going forward and large-scale combat operations is going to be counter-mobility. It's kind of that you know hasty transition to a defense holding key to rain and we really bring a lot to the fight there because we do have such a deep tool belt of obstacles that can help maneuver commanders shape engagement areas to to best suit their abilities to kill the enemy. So that's kind of what we're doing today is helping the maneuver commanders shape this area with with our obstacles.
