Nothing laughable about it. Many Russian troops are getting killed by such weapons.This is all laughable equipment and you know it.
1. US/NATO won't commit their soldiers to Ukrainian cause.
2. Leaving the Ukrainian forces to fend for themselves with inferior equipment is just a face-saving exercise.
If that was easy why Russians keep losing aircraft?What difference would it make. Russia will loose some equipments and men, while Ukraine will loose men, equipment and further land. These artillery can be easily taken from the air.
