I wonder if Taiwan is looking into these boat-drones considering their successes. Could be extremely useful in keeping any Chinese ships from ever landing.
Every single military in the world will be watching the usage of all sorts of drones in this conflict. Even if you're America or China you need to learn how to defeat them cost-effectively
Even simple unarmed $300 drones with an IR camera are proving to be extremely effective. The level of live battlefield information and situational awareness they are bringing to commanders on the ground is at least equivalent to what a platoon of recon troops can offer.
Next up are the drones capable of carrying light loads like air dropped grenades or explosives than can take our expensive vehicles like aircraft. The return on investment for these systems are insane.
For few hundred $ you get capability that formerly was only provided by ATGMs, and it's several times lighter as well, not to mention increased situational awareness. Every military worth their salt will have to study it and countermeasures
For sure, hasnt the whole world learned that heavy expensive vehicles can be countered by relatively cheap munitions?
Even without air superiority Ukraine has made MBT's basically useless.
