Do they have the ability to "see" or attack through multiple canopy Jungle?
Can they fly, see and attack during a blinding monsoon?
If not - the NVA would soon discover that shortcoming and STILL be able to move unmolested through much I Corps.
What WOULD have been great in Vietnam -- was SERIOUS and UNRESTRAINED large scale attacks against infrastructure, dams and civilian populations in NORTH Vietnam and the rail/road/bridge links between North Vietnam and Southern China.
The North could replace everything we destroyed or killed before we could fully refit/redeploy for the next onslaught .
The SAME error of allowing our enemy SANCTUARY in his homeland -- was made, as we are now making in the Middle East..
Fight like WWII, end like WWII.
Fight like Vietnam, end like Vietnam.
As our brother TomasUSMC has often warned.
No doubt, triple canopy would make this ineffective, as would severe monsoon rains.
I’m writing the insurgency in Tennessee part of my new book. It’s winter, and there is very little canopy at all. The best the guerrillas can do is move during bad weather, when the UAV sensors are ineffective, or the drones are grounded.
I’m looking for other potential ways to counter them, and not coming up with much.
Of course, a lot of their effectiveness is based on perception. They can see everything in a small area, most all the time, day or night. But they still need guidance based on intel. They can’t see all of a vast area all the time. When they do find and kill some terrorists in Iraq or wherever, that victory is trumpeted,and puts the fear into many other potential enemies, makes them afraid to move around outside for fear of a missile from nowhere.
Don't focus to much on just the flying robots
Visualize little robots the size of cats being dropped to crawl around on the ground, crawling up trees near indications of traffic, and sitting there waiting for somebody to pass by.
When it senses movement, a video feed goes up to an orbiting UAV to relay to a human at HQ, who decides whether to drop a bomb at the coordinates
