As far as I am aware, Russia has not pursued an image-seeking approach to anti tank missile design, let alone with fibre-optic man in the loop update. Why not?

What Am I Missing Here?

Such seekers are pretty expensive and Russia's developers weren't exactly good in regard to imaging infrared sensors (and maybe still aren't).
IIR guidance in ATGMs is furthermore very susceptible to rapid multispectral smoke (and by today rapid = 0.8...2 seconds till the line of sight is broken!) and thus IMO overrated in the West.

Main reason is decision that it is better for platform to be more expensive and missile to be cheaper.

Igla, R-73 and few other say you missed a lot of things.

From the Russians I have spoken to, they want such weapons and they want them very badly. Something like the Israeli Spike family of weapons would be exactly what they're after.
However, the current Russian re-armament program is often stymied by the fact that Ukraine is not on friendly terms with them. A large percentage of the old Soviet aerospace development and production infrastructure was in Ukraine. A fair number of missile systems needed parts made in Ukraine. Russian companies are in the process of reverse-engineering them so substitutes can be produced in Russia proper, but this takes time. Many plans for modernization and re-armament are years behind, largely due to this.

Also, they have no money.

"IIR" was no typo. I did intentionally not write merely "IR". The existence of one or another IIR sensor from Russia (such as IRST) doesn't suffice to prove that the Russian developers were good at it anyway.

I really liked your idea of a hypervelocity unjammable inertially guided missile/rocket that would be comparatively inexpensive and highly lethal.

Recent history tells us which is a better way. I would argue that Islamic State is a competent enemy that would kick the snot out of most of NATO. If it was not, NATO would not be hiding in al Tanf.

Funding? Also don't they already have a lot of barrel launched laser guided stuff? The US still just uses TOW, albeit Javelin is a much more modern system.
The Soviet/Russian GLATGMs are laser beam riding, not laser beam homing.
Laser beam homing missiles have a sensor in the front that looks for the reflected laser light from the target. The launching vehicle, or some friendly infantry units, shine a laser designator on the target and the missile/bomb steers itself towards it.
Laser beam riding missiles have a sensor on the back of the missile. The launch platform for the missile shines multiple coded laser beams at the target. For sake of example, we'll say it's four beams. Each beam covers a quadrant, and the sensor on the back of the missile can tell which quadrant it's in from the coded signal in each laser's quadrant. The missile attempts to center itself relative to each of the four quadrants, which results in it flying more or less straight down the path of the laser.
Beam riding is much cheaper, but also more limited. The sensor doesn't have to have any sort of angular resolution, it just needs to be able to detect the guidance beam and de-code it to determine which quadrant it's in. The missile is limited to engaging targets that are in direct line of sight of the launching unit, there's no way to hand off the missile to a spotter. Beam riding does have the advantage that it's pretty difficult to jam.

It's not my idea, of course. It's been researched since around 1980.

And no, russians don't really "want it badly". Technology is there and was there for decades, with TV used firstly with vidicons, later with matrix in seekers since late 70s. "They don't have money" hardy argument too.

How do TV (CCD) and IIR fail on range Gargean? The longest range ATGW in current use use these guidance types and have to do so because they're non line of sight.
Also, unless I'm mistaken, the scale of issue of image seeking ATGW in western armies is not significantly less than their wire guided SACLOS predecessors.

Another strange omission is the US Army's apparent disinterest in deploying a modern hand held anti tank weapon along the lines of NLAW or Pzf3
There was the FGM-172 "Predator" SRAW, a top-attack weapon that worked much like the NLAW but they stopped procuring it years ago from what I've read.

Spike SR is a most interesting weapon, often overlooked. It needs no launcher, weighs as much as a Panzerfaust 3, can do IIR-guided direct attack over 1,800 m and needs no launcher. Should be fine for BMP plinking on open fields.
ERYX is impressive in its range class, too. Short time of flight makes me wonder if the SACLOS vulnerability to IR jammers matters at all in this case, weight similar to Panzerfaust 3 but much better warhead and accuracy.
------------------------
Generally, I suppose one should draw a line between MBT-ish threats on the one side and BMP/BTR threats on the other (the usual BMP and BTR, not the super-uncommon heavy ones).
BMP-2 don't require a bigger warhead than 50-76 mm, depending on warhead tech, impact location, impact angle and whatever is outside of the BMP-2's main armour plate there.
Light munitions of less than 3 kg can be developed to be effective against a moving BMP-2 at ~500 metres. That's something that we're missing.
You need heavier munitions than infantry could carry all the time for anti-MBT work.
I suppose infantry should have short range anti-MBT munitions in its vehicles (Pzf3IT-600, for example).
Long-range anti-MBT work is either about delusions or about heavy vehicle-mounted weapons and munitions. Ideally long rod penetrators by 120-125 (soon maybe 130 mm) calibre or CKEM-ish.
Portable ATGMs of all kinds can be defeated all-too often by competent, alert and well-equipped crews (neither Turks nor Saudis are a proper benchmark). Especially the rapid multispectral obscuration is most impressive - and cheap!
GALIX was good
(sorry for the obnoxious narrator)
but this one looks even better:
https://www.youtube.com/watch?v=cu7daHh7-PA
So the gaps that I see are
(1) ultralight anti-BMP munition with 400-600 m effective range (3 kg and predicted line of sight autopilot), carried by every infantry fire team in all combat situations
(2) anti-tank HVMs with long rod penetrator and inertial navigation autopilot for predicted point of impact flight, mounted on vehicles
Instead, there are lots of 5+ km ATGM systems; missiles for ranges at which detection and identification of targets is most unlikely unless you want to fight in Russia, Ukraine or Arabian deserts.
There are also way too many WW2 bazooka-inspired 'dumb' "anti-tank" weapons and munitions with horrible inaccuracy and marginal effective ranges.
The modern Carl Gustavs are fine, but they're man-portable infantry guns, not anti-MBT weapons.
There was the FGM-172 "Predator" SRAW, a top-attack weapon that worked much like the NLAW but they stopped procuring it years ago from what I've read.Another strange omission is the US Army's apparent disinterest in deploying a modern hand held anti tank weapon along the lines of NLAW or Pzf3
Those were few, reworked into HE munitions and by now I suppose many if not most were expended.

They failing range due to both LOBL and weight points. Jav have so limited range mostly due to IIR head needing LOBL. Can be neglected with LOAL capability like in Spike, but full seeker in any case would eat a lot of weight that otherwise would be used for range keeping.How do TV (CCD) and IIR fail on range Gargean? The longest range ATGW in current use use these guidance types and have to do so because they're non line of sight.

Seeker also tends to be in front of shaped charge, reducing the penetration by acting as layers of a whipple shield.

Chris, you really are a fossil. The scale of issue in Western armies is dismally poor in reality because everything is on paper. The shortfalls in actual ready rounds is generally glossed over thanks to the lack of combat usage.
The new reality is that guided missiles are useful for shooting everything up from pickups to personnel and that you need as many as you can scrounge out of legacy stocks. They are also having to be issued on a much wider scale to defend against SVBIEDs which will continue to be a major problem going forward because it's not just Jihadis who are willing to martyr themselves.
The Russian beam-riders are really cheap. Yes, you can deploy screening smoke but only if you notice them incoming. And they are supersonic so they arrive before any audio cues.
