what are the details about where this was? was it an apartment, a house, a farmhouse? was it isolated, or in a dense area? I imagine if it had been even slightly isolated, they just would have used a precision bomb strike to take it out - why storm it with troops and take KIA and wounded? you've got to believe they know that he would not be taken alive.
From what I have gathered, it was a house in Mosul.
That's my point, they wouldn't have raided it had they known for sure if Zman was in there. I think this entire episode kinda fell into their lap, so to speak.
They raid houses all the time over there. It's a relatively simple objective, get in, check it out, if you find something, that's good.
