More than 100 members of Britain’s elite special forces have been sent to Ukraine amid fears a Russian invasion is imminent, Report informs referring to the Daily Mirror.
Crack troops from the SAS, the SBS, the Special Reconnaissance Regiment and the Special Forces Support group are understood to be working in the country as military advisers.
They are believed to be helping train Ukrainian special forces in counter-insurgency tactics, sniping and sabotage.
British special forces have been able to deploy such a large number to the region as they are no longer operating in Afghanistan.
Although the SAS and SBS are still in Syria and Iraq, the numbers of troops there are believed to be relatively small.
At least 1,500 winter-trained British troops are also now based in Estonia, which borders Russia.
Meanwhile, Russia has started equipping dozens of military field hospitals close to its border with Ukraine, fuelling fears of an imminent invasion.
Intelligence sources say doctors, nurses and medical supplies – including thousands of litres of blood and plasma – have arrived in the region, where fighting would be the most intense.
