I know people who are very screwed up after having to shoot children carrying weapons because their parents told them to. I know people who've had to make the kill/no-kill decision on a woman and her child approaching a convoy. It's a fucked up situation. That's why we try to avoid war.
You can't just deploy operators when a guy goes home to his family. It's expensive, dangerous, and difficult. If you leave him alone he could be ordering people from his home to kill your people. Unconventional war is by definition unconventional. If they fought like a regular military their families would most likely not be targeted. I have no data but I can tell you absolutely no one wants to kill women and children. Except for hamas, that is.
