The Marine 8x40, 7x50 and 10x50, and 7x50 compass have the same design as the Chinese military ones.  The military features of the Marine binoculars are: they have ruggedized all-metal rubberized body;  They are nitrogen purged and are as waterproof as the military ones; they are shock resistent - drop them from 5 meters high, the prisms are still dead-on.  The lens are made in a low-grinding process (compared with the high-grinding for most of the non-military binoculars) to achieve the best optical performance possible.  In fact, they are the same as the  military ones except that they are not coated in the same way as the military one and some military parts like reticle are removed.  Optically and mechanically, they are just the best all-purpose (40mm and 50mm) binoculars made in China.  

The Marine binoculars come with Bak-4 prism, broadband fully  multi-coated, individual focus, brass 1/4-20 tripod adapter threading, hard leather case, caps, and strap.
