Cool idea, but chances that a military buys these outside of a couple token models, very slim. It looks extremely expensive and militaries cannot afford to place that much value on a single front line solder
The UK and US already probably spend more than that on the evac of our troops, and if it means they can evacuate someone that is stable without sending in a many million pound copter complete with 2 fully trained pilots and 2 or more other aircrew they are very likely to do so. Maybe not that model, but something similar especially if say someone can make them cheaper than the cost of training a couple of soldiers so it only has to save one or two lives for the financial benefit to outweigh the initial cost.
Even at 100k or more each it's a lot cheaper than the loss of experienced soldiers (once you allow for training and the insurance/death in service payments), let alone the loss of a normal helicopter.
Western military forces will spend a fortune in protective equipment and training to try and reduce combat losses, then another fortune in attempting to recover the wounded as it's far better for morale and overall cost if you can, at least with Western type professional armies where you tend to get a lot of time and money invested in every serviceman, especially once they've been in the forces for a couple of years.
I suspect you'll also see them being sold to the likes of search and rescue and used in mountain rescue operations, as if it can carry a wounded person out it can potentially carry equipment in as well to help stabilise them for the lift or help additional injured.
Basically even if it's "expensive", our armed forces are already willing to spend far more to recover injured service people, and risk far more as one of those drones won't even come close to the potential cost of replacing a medevac pilot, let alone their aircraft, and they are far less likely to lose a smallish drone than a full size copter.
