Not to get into the debate about that other war, but there have almost certainly been many more Ukrainian civilians killed than the 11 000 formally confirmed deaths. That's just the number that can be properly verified, mostly in Ukrainian-held territory, and nobody is entirely certain how many have died in the Russian-occupied regions. Ukraine claims a much larger number have died, including more than 25 000 in Mariupol alone, for instance, but that can't be independently verified because it's still Russian-held.

Usually you would compare it to other instances of urban combat.

E.g. you might compare it to ukrainian battles that took place in cities, but you wouldn't compare it to ukrainian battles that took place in the middle of nowhere where no civilians were. https://en.wikipedia.org/wiki/Civilian_casualty_ratio has some things to compare against. Part of the problem is it is often hard to identify who is a civilian, and often different battles will categorize them differently. For example, in the iraq war us was accused of significantly undercounting civilian casualties. All this makes it hard to do direct comparisons.

A similar anti-terrorist war featuring large amounts of urban conflict, eg Iraq (3:1) or Afghanistan (4:1.1) — since much of Ukraine is designated armies across open fields.

Ukraine's troops are uniformed and fighting along a front, not trying to blend in with civilians in an urban area

Since we're quoting might as well: "Under the cover of thousands of rockets fired from Gaza, they killed indiscriminately in streets, houses, kibbutz communities and at a rave music festival.

It took more than three days of heavy fighting for the Israeli army to regain control, and left the country deeply traumatised by violence unseen since the country's formation in 1948.

Police are still working to assess the scale of the sexual violence that was reported alongside the killings."

I'm pretty sure "security forces" includes police and possibly firefighters and even ambulance drivers. What I found in the IDF site is 282 soldiers: https://www.gov.il/en/departments/news/swords-of-iron-idf-ca...

So the ratio is more like over 3:1. More importantly your statement not true ("civilian to soldier").

Much of that was Israeli friendly fire
