> Not sure if that is better than just using a helicopter however.

Anyone who has done first responder training should have had it drilled into their skulls to remember the number one rule .... "do not add yourself to the injury list".

If you're operating in a war-zone its kind of the same thing. Send in a helicopter to drop off one or more guys and you are also sending in bare minimum of one extra person but realistically almost certainly three extra people (two at the front and one at the back to watch the people jumping out).

Also drones are probably somewhat cheaper than helicopters. Both to buy and to operate.

There’s no way anyone is getting a helicopter anywhere near that front line.

Transporting wounded soldiers has become a significant problem in recent years.

Because it's not America with Vietnam/ Iraq war mindset.

Helicopters are extremely vulnerable for drone interceptors. With Recent developments, the an interceptor can fly up to 600 km/h. It can also wait for you on the balloon.

Overall, piloted aviation, it's almost a dead end with all the recent capabilities.

Probably harder to hit six single-soldier carrying drones than one helicopter.

A lot of the wounded soldiers that are getting these heroic evacuations have lost weight, months of combat and limited nutrition, blood and limb loss.

Fresh soldiers, with a combat load, might be too heavy. Or simply risky

Can not see the drone and shoot it down using thermal camera or ir seeking missile
