Royal Observer Corps Monitoring Posts, known more commonly as ROC posts are underground bunkers type structures all over the UK. Over 1500 of them were constructed as a result of the Corps' nuclear reporting role and operated by volunteers during the Cold War between 1955 and 1991. Generally they were manned by 3 people 24 hours a day to monitor the possible event of a nuclear attack. *GUNS, FUN AND CAMOUFLAGE DISCOUNT* FOR 10% OFF AT GUNS, FUN AND CAMOUFLAGE IN WALTON-ON-THE-NAZE ESSEX, PLEASE SUBSCRIBE TO OUR YOUTUBE CHANNEL AND LIKE THEIR FACEBOOK PAGE FOUND HERE.. www.facebook.com/GFandC/ WHEN MAKING YOUR PURCHASE MENTION THIS OFFER TO RECEIVE YOUR 10% OFF!
