This right here is why the PLA only release silly pictures. Because the ‘pics or it didn’t happen brigade’ can’t or won’t apply even a little bit of imagination and common sense to look beyond what has been literally shown to see the obvious potential.
If such drones can drop MREs, what’s stopping them dropping off ammo to a besieged and/or cut- squad so they can hold out until reinforcements can reach them?
Similarly, such drones can be used to drop off specialised medical equipment/supplies to save soldiers’ lives; or specialist mission gear you would not expect troops to carry with normally.
That, in turn opens up all sorts of possibilities in terms of how you equip your standard squads. They could potentially not need to hump a lot of low probability of use gear since those could be rapidly dropped off to their location when actually needed.
On the flip side, cargo drones can be dispatched to exfil high value intelligence caches regular grunts come across on the ground.
The possibilities are almost endless, not no, let’s all instead just laugh at how silly it is to drop off MREs. Because we all know once you load a drone with MREs, that’s all it can ever carry.
The use of drones to resupply, even in such a tactical manner, is not controversial, even if it is just here demonstrating a resupply of some meals.
But what is somewhat unimpressive here -- or at least uninspired -- is the half hearted adaption of an off-the-shelf consumer multicopter drone in providing the resupply (I think this is a DJI Matrice 600).
Consumer drones obviously have their role in certain domains of modern warfare if you don't have anything else, and for some roles, consumer drones outdo custom made military drones (short range tactical recce is one aspect where foldable mavic drones can outdo most competitors at its given performance/cost point).
This is an example of the PLA using a very low effort, off the shelf solution that might have been done as part of primitive experimentation/demonstration of resupply by a non-sophisticated UAV, which doubles as a photo op that might impress your average person on the street who doesn't know anything about consumer drones and the sort of requirements for drones in a true wartime tactical resupply role.
Overall, calling it a low effort photo op that is at best "neat" is about right.
It certainly isn't very impressive, but that's fine as well because there's nothing wrong with having some average or lame pictures now and then.
