You can fact-check me on this if you want but soldiers on leave from active duty are not considered combatants and so are not supposed to be targeted.

There was a comment by an Israeli soldier way back at the start of the Gaza thing that stayed with me but I can't find it now of course. He was commenting on the tactic of bombing residential buildings at night with everyone inside asleep to get one Hamas operative. He said something along the lines "imagine if they came after us when we were at home on vacation" or something like that. I don't believe anyone thinks that's fair, or legitimate, or anything of the sort, it's just something that can be done, so it's done.

The way I understand the article above is that there's not even a clear motive anymore. The AI says "bomb them", so they're bombed, end of.
