If you pack all the russian mines in Ukraine in a line its probably long enough to reach the moon from earth (and back).
Breaching the minefields under heavy enemy fire did not work
They had massive problems and losses from attack helos, it took months and lots of begging to receive ATACMS to reduce this threat a lot (by killing a dozen Ka-52 and forcing the other to bases way back).
The west was (and still is) too afraid to sent longer range weapons.
The Ukraininans have to keep the pressure up in their offensive zones (to advance and to fix russian troops) and in the russian offensive zones they have to make sure to turn those into killing zones without losing too much ground.
