And the recent drone tech is saving many lives and lots of money.

Guess it's better than dropping nades on top of you, maybe :/

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.
