Pure speculation.
I’d like to know if there were other entities on the raid alongside us.
Could have been a security leak from our so-called “partners”—the enemy knew we were coming.
“investigation going on to determine how the Yemeni terrorists learned about the attack.”
Not disagreeing with you but,
I would think that on a stone cold moonless night, in the mountains, an Osprey hard landing (AKA crash) would have made a s*** ton of noise. The fact that the troops then had to traverse miles to get to the actual site, would have woke up everybody for miles and given them plenty of time to lie in wait and set up an ambush.
Element of surprise, for this Op, would’ve been paramount. I don’t see how it would/could have been possible to achieve under the circumstances.
