Tanks are sitting ducks. Especially in insurgency warfare. They offer a false sense of strength, invincibility, and superiority. They will rely heavily on infantry and other defenses to protect them.
When LNs have sufficient weaponry (which is very prolific today) to defeat tanks, at almost no cost to the LNs but a huge loss to the side relying on armor, the LNs will prevail. Tanks cannot be built and replaced as fast as they can be destroyed.
This was a lesson the Germans learned in WWII. They had the best armor of the war, certainly better than the US. They could routinely and repeatedly beat 4 Shermans in a tank war, so it would take 5 Shermans to destroy a Panzer or Tiger. But the US had 10x as many tanks. So it became a war of attrition. The winner is the survivor.
Same with anti-armor weapons, which can be delivered from afar or by drones, or mines, VBIEDs, traps, etc. LNs can bleed the Russians dry of tanks, armored vehicles, and aircraft which cannot be easily or cheaply replaced infinitely. The LNs will have infinite supply of anti-armor weapons.
