Every Arab Pali living in Gaza is a civilian:
* Some, not being in any nation's military, are "illegal combatants"; i.e. Hamas terrorists;
* Some are Hamas logistics;
* Some are non-Hamas, but giving shelter and material aid to Hamas terrorists and logistics operatives;
* Some "merely" celebrate the murder, rape, and abduction of Israeli civilians;
* Hypothetically, there may be some or a few Arab Palis trying to keep out of the whole mess; whether there are any such is hard to tell, since they would be trying to be invisible, to Hamas as well as to the IDF.
