Well they knew they were in an area with poor comms and that happens. I ran missions without good comms plenty of times. I believe they expected that they might miss a few check ins.
But yes, the mission was a giant cluster fuck to begin with. And I can't speak for the SEAL community, but I can speak on what I saw with my own eyes. Because of my security clearance you need for Marine Recon, I was pulled to run as security attachment to one of the teams in Ramadi. I wasn't allowed full access to their intel but it was good enough to sit in the vehicle with them and go post up as a security element while they did their thing. We did various raids on HVTs, we found some huge caches and had some gun fights. All in all... I just wasn't impressed. And I catch shit every time from fanboys but I watched a shit show for several weeks.
