Hi all. This is a sleep system that would be great to get into the Army's hands, but for now the USMC has it all to themselves. It's extremely well thought out, and works great when used properly. It replaces the Modular Sleep System (MSS) which was developed by the Army in the 1990s. See below for the system NSN's and components. Also, here's a video that explains how to properly employ the system. https://youtu.be/2JmLTnZUiJI
