The Large Spec Ops sheath will fit the YardGuard with a minor mod.
It is Molle compatible and matches the uniform well.

The smaller Wak sized version of the AK known as the Ruck was designed specifically for a US SF unit as a close combat weapon that would fit in a Rucksack. Now it may seem strange when most would use a rifle or subgun but if they were looking for a terrorist cell in say an country like the UK that both has strict gun control and would not allow a foreign service it could be very handy.
Terrorists have lots of time to source weapons but it is doubtful you could find anything black market if it was an emergency.

My current EDC would be the same thing I would carry into combat. My beloved SS4.
I bought it thinking it would be one really good knife so i would not need any others. It turned out I was right. I did not NEED any others but I sure as hell wanted them. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
