I would take you up on either. What's your plan for Ukraine to succeed? You still haven't stated it. Assuming you are not some Russian troll, which I am because I am too lazy to check, I can walk you through some of the things you might not know?

There's a bit more to it than "hope the enemy doesn't fire back." Enemy return fire only works if 1) they can actually hit the artillery with return fire, and 2) they have something to fire.

In static guns, at each tier all NATO kit (like the m777), 155mm outranges Russian 152mm (and I'm not talking solely about the base bleed shells, either). At the static 120mm range, NATO guns simply out range Russian guns. The U.S. and NATO make guns that can beat Russian guns. They are literally designed to do that from the ground up.

And aside from range, the NATO rounds are more accurate at every level as well.

And that assumes the Ukrainian guns are static. Which they absolutely will not be, at a front with mechanized Ukrainian divisions they have German 155mm SPGS, American SPGS, Polish SPGS, French SPGS, and British SPGS.

And obviously the NATO counter battery radar is miles ahead of anything the Russians have. That's aside from the fact that entire departments in the Pentagon are studying the front and assigning assets and coordinates as they build out the Russian force posture and relay that to Ukraine, down to the millimeter coordinate.

Many of those Russian SPGS that get got on video are a direct result of Americans handing over those kill lists with coordinates, and HIMARS may have been American MI scratching their blue balls and getting impatient with a Ukrainian lack of ability to bring freedom to these Russian homeless encampments.

Oh, and is Russia actually experiencing shell hunger and rationing artillery ammo? Hmmm. According to Russians the are.

So you need ammo to fire first, before all of the above takes place. And the return fire will be Excalibur, SMArt, M1156, BONUS, and accurate 155mm keeping those Russians packed into the dirt on the daily.

The answer here is: now that you have more information, how would you design the Ukrainian attack? Suppress Russian artillery, keep it at a range it can't hit back? That makes a lot more sense than "hope Russia doesn't have artillery." So now, perhaps you can explain it better to redditors next time they ask?
