Medical privacy ends when the condition may cause detrimental effects to other people. It’s not that difficult of a concept to understand.
Somebody who has epilepsy is not allowed to drive vehicles or fly a plane. They might have an episode while operating the vehicle and kill/injure others.
Somebody with a confirmed deadly disease is not allowed to wander around spreading it to others. Their decisions to ignore quarantine restrictions will kill/injure others.
Long range attacks are about knocking out supplies, the ability to produce new supplies, and the ability to get supplies to the front line.
Say Russia is getting more newly made artillery shells to the front line. The best way to fix this is to blow up the factories.
If you can’t take out the factories directly, take out components that the factories need to operate: ore processing, fuel refineries, electricity grid, etc.
The problem is all the critical targets are a long ways from the front line and Ukraine currently has limited capacity to hit them.
Meanwhile Russia is targeting all of Ukraine’s internal infrastructure constantly.
Long wars are won by the production capabilities of the groups involved as much as the front line troops.
