LONDON, Muharram 28, 1436, Nov 21, 2014, SPA -- Britain is carrying out its largest armoured deployment in Eastern Europe for six years, in a joint exercise with Poland to reassure it in the wake of Russia's intervention in Ukraine, Reuters cited the Ministry of Defence as saying on Friday. Last month NATO-member Poland said it was drawing up a long-term plan to shift some of its military strength towards its eastern border, following Russia's annexation of Ukraine's Crimea earlier this year. Britain said around 1,300 of its soldiers were taking part in the bilateral UK-Polish field training exercise in southwest Poland alongside a Polish cavalry brigade and tank battalion. -- SPA 22:07 LOCAL TIME 19:07 GMT www.spa.gov.sa/w
