So UK citizens were not kidnapped? Or are you implying the UK were not doing intelligence flights, but were attacking Gaza directly, or had boots on the ground directly? Because I have seen absolutely zero reporting to infer that.

Well the Russian drones are munitions, so that's not comparable. Is the UK dropping bombs on Gaza? I have seen zero reporting to say they have.

The UK might be flying spy planes outside it's airspace when it's citizens were kidnapped. That's not a "combatant". Was the UK a combatant when flying spy planes near the Ukraine border?

I think you are way off the mark based on reporting, I'm not even sure how you are coming to these stated opinions.
