On July 24, the Palestinian Center for Human Rights said that the IDF killed Mohammed Barham Abu Draz, who they called a "civilian."
He was a member of the Hamas Al Qassam Brigades. Here is his "martyr" poster and video, from a Facebook page memorializing him:
And here is Draz with Hamas leader Ismail Haniyeh and (I believe) Fathi Hammad, during his day job when he wore the red cap of Hamas security forces.
The PCHR claimed that Hayel Shihda Abu Dahrouj, 28, killed on August 23, was a civilian.
He was a member of Islamic Jihad's Al Quds Brigades.
