Ukraine Is Winning The Artillery War—By Destroying Four Russian Howitzers for Every Howitzer It Loses

So this is why they're using those old tanks as artillery (besides the ammunition shortages)

That only works for so long depending on how many artillery pieces Russia has in reserve / can move to the front. Of course, NATO can keep Ukraine topped up, so on balance I think Ukraine will come out ahead.

I was hoping the ratio was even higher. 1/4 would mean over 1000 artillery pieces and therefore personnel lost.
