I think it means we don’t want to be like Russia and destroy Civilian residential buildings and homes.
I heard stats that Russia has killed 9000 Ukrainian soldiers and 20,000 civilians.
Russia just lobbies shells indiscriminately. Their Special Operations is “liberating” a lot of Ukrainian civilians from this life.
That scenario is already established in LOAC.
We prohibit attacking civilians without a true military purpose.
We can attack industry that is manned by civilians performing a direct military purpose, whereas we can’t attack civilians like farmers.
