Every soldier is keen to have access to a good surgeon in the heat of battle, but those suckers don’t come cheap, and if your doc buys the farm, it can take some time to fly in another one with the same expertise. Now there’s a way to keep the sawbones away from the battlefield but still make use of their life-saving skills – they can operate on you using a machine controlled by telepresence from miles away. It’s a great idea, but I imagine it’ll take a while before soldiers (or anyone else) are completely trusting of an anonymous machine with moving scalpels and needles.
