 This training kind of really hones in on a lot of aspects of the first Marine Division, like of a warfighter. It makes us communicate. We're obviously shooting and moving. We're testing all of the abilities that we're supposed to have during the daytime, and then we're doing them at night, which just makes it a little bit more complex and challenging. Testing our ability to function in the nighttime and utilize the equipment that we have, how proficient we are with our night vision devices, how proficient we are with our night aiming devices, things like that. Really test communication at the small and higher unit because you no longer have the visibility that you do during the daytime. Can't always rely on comms, so building plans that can be executed based on conditions and things like that is really critical during the nighttime whenever you can't see and communicate as easily.
