Looks impressive, but a short burst from a mp5 would take them all out in seconds unless they were suited in full body armour.
Then there’s the noise from those screaming jets......
No surprise attacks and no covert boardings.
probably some use if we could drop a pack or 2 for a downed crew to quickly put some distance between themselves and an approaching enemy.
Fitted With standard off the shelf drone circuitry I can see those “packs” being parachuted into a location to enable the self extraction / escape of a seal team.....suit up and press start...jetpack then automatically “returns home” or removes the “captured target” to his new home.
rescue uses in inaccessible locations ? How about parachute a medic and spare pack into a very remote bush or mountain area, have him suit up the injured party and deliver them to the ramp of a low flying herc ?
all sounds very James Bond right now but look at the advances in recreational drone technology recently , Given time the jetpacks will evolve to be quieter with better fuel burn, by then its uses will be limited by ones own creativity.
