the cruelty is the point

Because of the uranium bullets are denser and heavier than the lead bullets and you can use the uranium bullets on certain types of aircraft and other weapons systems to shred through medium to heavy armor that could not be penetrated with a lead bullet. TLDR this will be used as a force multiplier.

They are harder and penetrate armour better. So yes they will provide an advantage.

The sooner Russian occupiers are no longer murdering Ukrainians and dropping mines over every square meter of land, the less harm comes to Ukrainians.

Russian forced are mechanized and entrenched, depleted uranium self sharpens on impact, yielding far better armor penetration than previous technologies.

No individual measure aside from troops on the ground or nukes is going to change the course of the war by itself.

The ammunition is very effective at punching through the armor. But the Ukrainians will be fucked when in 5 years Leukemia in children is skyrocketing

Ammo is ammo. It's better than hurling stones.
