Vehicule don't look destroyed but have probably lost the soft parts functions like radar and optical sensor systems. All these fragile sensors are probably in huge demand in repair yards and I can see the utility to field rugged low tech systems that don't require them. Dropped mortar and grenades, zala drones, switchblade, artillery all of these are probably eating tons of subsystems.
I see the new generation of MBT with all the bling bling cameras and sensors and I see the fields of Ukraine with 1m of mud and the air filled with shrapnels.
Not sure that everything is going in the right direction in developments for that kind of conflicts.
It is not related to the quality and quantity of the sensors, but rather the integration cost and time, including testing.
There is utility for every extra sensor, with bigger resolution and so on,but it is not just plug and play, it has to be evaluated and tested with in context of the full system, including maintanance, cooperation with other units and so on.
Of course it is long and expensive process, so every western military supplier feel the inciciative to sell a brand new sensor only, and left the cost of integration for someone else .
I had fancy story, when a purchasing guy realised that to buy the components of the manufacturing cell ( machines ,robots and gauges) vost 50-70% than the quote for the full , deployed kit.
So, he bought the pieces, pocketed the bonus for saving,and caused a huge drain on the engineering department resources.
And of course the deployment was 5* longer and cost more than the original quote, but part of the new cost was internal. And he already gone for a new position .
