There were several abandoned vehicles with fuel, as well as they were still in working condition, how do you explain this?Whatever the case, if a vehicle has not been lost to combat, then it could only have been lost to logistics. Either it has no fuel, or it broke down and there are no recovery vehicles nearby, which is also part of logistics. The fact remains that abandoned Russian vehicles, including fuel trucks and supply convoys, are photographed every day by Ukranian civilians behind Russian lines. This is indicative of a significant level of attrition, i.e. more than just a few vehicles getting stuck or running out of fuel.
Another thing, there is a difference between a combat and support vehicle having been abandoned due to being attacked and having been neutralized, making it impossible to use, and quite another is abandoning due to lack of fuel. Yes, there were videos that the vehicles were in working condition but out of fuel, but most vehicles we didn't have that confirmation. You clearly didn't make that distinction. This is far from a logistical failure.
