Could this new Nato device be the difference between life and death on the battlefield?

In the heat of battle, medics have to be prepared for injuries and casualties on the battlefield.

They are faced with making a number of choices in a split second – who needs attention right away, who doesn't and whose injury is too bad to help?

A new device is being developed by Czech Technical University and Nato to help medics make that decision.

• Royal Navy autonomous minehunter 'Harrier' to trial uncrewed operations in the Gulf
• Future of forces aviation? The world's first modular military jet

A new wearable monitor helps medics make those life-and-death calls on the battlefield by creating a digital hub of medical data, as explained in the video above.
