DEPLOYING thousands of military personnel to assist with the coronavirus pandemic is "risky", a defence expert has warned, as the UK Government announced it intends to bring soldiers back from Iraq.

The UK Government stated yesterday that up to 20,000 service personnel will form part of a Covid Support Force.

And today it announced troops would be redeployed to the UK after a training mission in Iraq was paused for 60 days due to the global pandemic.

The UK will retain "key military personnel throughout the country" to ensure the interests of the Iraqi Government and Global Coalition are appropriately supported.

But Elizabeth Braw, senior research fellow at the Royal United Services Institute (RUSI), said the tasks troops would be expected to carry out in the UK were "not their speciality" and "essentially a distraction" from their normal duties.

She said: "With something like this, it is not exactly clear how the armed forces can support and more importantly we have to consider that they may be needed elsewhere," Braw told the PA news agency.

"We can't take for granted that we will only have a virus outbreak. What if there is another contingency, and I think that is the danger in relying on the armed forces.

"To always assume that they will always be available to help with these kinds of duties that are not their speciality and are essentially a distraction from their speciality is risky."

The Ministry of Defence (MoD) said it was "fully engaged" with all levels of Government to work out how the military can provide a support role over the coming weeks and months.

As part of the Covid Support Force plans, 150 military personnel will be trained to drive oxygen tankers for the NHS, as well as providing general public support, the MoD said.

Armed forces minister James Heappey downplayed the severity of troops' involvement, after a video appearing to show several vehicles transporting tanks along a motorway raised speculation online.

"This is when social media is at its most ridiculous," he wrote on Twitter.

"We've got plans for offering all sorts of support during the Coronavirus outbreak. But absolutely none of them, not even one, involve tanks!"

Around 10,000 troops are held at "higher readiness" in case of a civil emergency and this figure will be doubled in the effort to support public services amid the coronavirus outbreak, the department said.

Braw, who heads the RUSI Modern Deterrence Programme, suggested that in future "ordinary civilians" – including teenagers – should be trained to support in times of crisis.

"It's good that (the armed forces) can help this time, but it does raise the question of what we should do differently – this time it is too late, but for future contingencies," she said.

"Maybe the answer is to have trained civilians who can step in and help the blue light services and other government agencies when there is a crisis so we don't always have to turn to the armed forces."

Military personnel have been enlisted to assist in previous national emergencies, most recently during widespread flooding caused by storms Ciara and Dennis.

During the 2012 London Olympics, some 13,500 troops were called to provide logistical support and venue security.
