This message board is here so you can view the latest additions to our NSN library. In addition, you can request new NSN's that you don't currently see listed. To do this, click on the "New Topic" button and make your request. So if you're looking for the NSN for a certain model of 5-ton truck, or a certain kind of power supply, or antenna kit, etc, just put as much information as you know: LIN, Nomenclature, or anything else that would be helpful. If desired, add an email / AKO address if you want a direct reply (this is not required). Then we'll do some looking on our end and see what we can find out. But...... we can't guarantee that we'l be able to find every NSN that people request, because of the difficulty in conducting detailed research on each one. (Assistance from the community would be highly appreciated, in cases where we're stumped!)

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.

1. Base "3S" 3-Season Sleep System.

Complete System NSN. Includes a, b, c (i or ii), d, e shown below.
Size Regular:
Size Long:

System Components
a. Bivy Cover:
b. Compression Stuff Sack:
c(i). Sleeping Bag (Size Regular):
c(ii). Sleeping Bag (Size Long):
d. Mesh Storage Bag:
e. Visual User Guide: NO NSN ASSIGNED.

2. Extreme Cold Weather "Module" (can be used in stand-alone mode, or together with the 3S system).

Complete System NSN, size "Regular to Long" (includes items a, b(i), and c shown below):
(The complete system is also known as the ECW SBM or "Extreme Cold Weather Sleeping Bag Module")
Note: There is no complete-system NSN for the "X-Long" size, at this time.

System Components
a. Compression Stuff Sack, also known as ECW CSS:
b(i). Outer Sleeping Bag (Size Regular to Long), also known as ECW OSB:
b(ii). Outer Sleeping Bag (Size X-Long), also known as ECW OSB:
c. Visual User Guide (ECW VUG). NO NSN ASSIGNED.
