Major Y [an American who went to Israel to fight] and other people on the ground I have spoken with say that they estimate about one in every two or three [civilian] homes in Gaza they go into has military weaponry, including AK47s, grenades and rocket launchers. And they routinely find entrances to Hamas’s terror tunnels inside civilian houses. And not just anywhere, but most often in the children’s bedrooms and even under cots.
Ftfy, the passive voice is too weaselly.
Unfortunately, I don’t agree with your sentence modification.
