An idea that our companies can adopt and refine and offer it to forces?

Okay...being the resident "infantry-gun based anti-UAV system" opponent of DFB, let me put forth my defence.
Let's draw a parallel between trying to shoot down an UAV with an ADS trying to shoot down a plane...this is what most people miss, that despite being small and slow an UAV is still an "A" and you'll need proper "ADS" to counter it.
In any proper ADS you'd have atleast two sensors (one acquisition, one tracking radar), one effector (either gun or missile) and guiding algorithm (either guns calculating lead to predict the impact point or missiles guiding themselves).
This would be bit too harsh for the comparison so let's look at a bare bone example; a two man MANPADS team with one member being guided by the HQ radar to look at certain sector of the sky for a target (something like Wolf2, this is Command, inbound target, sector 90, altitude 3,000 feet, range 10 kilometers, heading west, prepare for engagement) and if not this then the spotter would be standing still and scan the whole horizon with his binoculars for potential target.
Upon detection they'd have atleast 5km to react; (range of MANPADS is higher, a helicopter is bigger so it's silhouette would appear earlier, noise would be more)
Now for a 5 man squad moving through a city with one soldier equipped with anti-UAV gun. (Either a shotgun or rifle with speciality ammunition)
• A UAV with pretty similar speed (250km/h in dive) to an AH-64E (300km max)
• but extremely small silhouette (less than 0.1x) and thermal - acoustic signature
• instead of a long ranged tracking radar, you now have just Ears 1.0
• instead of a Ku-Band tracking radar, you now have just Eyeball 1.0
• instead of sophisticated impact prediction algorithm you now have Brain 1.0. (how difficult it's to calculate "lead, we've just one Olympics medal in Trap Shooting...I know it's a flawed argument, but for a rough idea)
• a soldier can't stay and scan the sky for long while his squad is moving somthing a MANPADS team can do
• the max battle range of even 7.62x51mm is 600m, for a shot-shells it'd be hardly 100m. (At 300m away, you'd get just 5.5sec to down an UAV diving at 200kmph)
• shot-shells are notorious for their "spread". You use smaller pellets to decrease the gap between pellets and now you're 1mm diameter pellet isn't doing much damage to the FPV. You switch to 4mm pellets to counter this and now the gap between the pellets increases to much. It's a paradox.
The most sophisticated system we currently have to use small arms for anti-UAV role with any degree of success are the smart sights like SMASH2000 and Arbel. But even with them, the weakest link in the whole system turns out to be the human using it; how far away can you detect the drone? How fast can you react?
Here's a great video of Ukrainians experimenting with shotguns. Point to note is that the drone is coming head-on in a straight line and they know from where the drone would come.
