It has been six months since the Russian military entered Ukraine and a former Chief of the General Staff has said the Russians have "failed spectacularly".
"Every possible military mistake that the Russians could have made, they made and a few more that we hadn't even dreamt of, and that attack from the north failed spectacularly", Lord Dannatt told Forces News.
Lord Dannatt believes the Russian performance has been a "surprise to any honest military observer from the West", adding: "I think we all credited them with a greater capability than has been demonstrated."
