I wonder why the title clarifies "for rescue ops".
Is there anything inherent to this technology that prevents it from being used for anything else? The article body insists on "demonstrations relevant to specific defense operations" which sounds quite broad and not limited to rescue ops in any way.
- Very fast - avoids radar/detection - water based
My first assumption is that this is for stealth ops. "Rescue" doesn't need those features.
It's too low to do anything else. Snipers would decimate an entire attack squadron.
It sounds less aggressive.
