I recommend this as your first book to read on the Russian martial art Systema!
Another MUST in your library that I have read by two former SEALs!. Referred to in Disappear & Reappear! ebooklet.
Former Special Air Services elite fighter Barry Davies KNOWS his stuff! GET THIS ONE ASAP!
ANY or ALL of former Navy SEAL Commander Mark Divine’s books are a MUST! I own it and referred to in Disappear & Re-Appear!
I own it!
