As cool as the trailer looks, I nevertheless have reservations about using SEALS and showing SEAL tactics.
I assume they haven’t shown their best tricks, but still...
Your concerns are shared by some number of people (although apparently not many enough by the look of things). One of them, retired Army Lt General James Vaught, told Admiral William H. MacRaven (Head of Special Operations Command) that 'One of these days, if you keep publishing how you do this, the other guy's going to be there ready for you. Mark my words. Get the hell out of the media.' There have been other members of the military who have also not been too pleased with all the attention the SEALs, in particular Tier 1 Assets like DEVGRU, have been getting. Not just the movie, but in particular how mission details are released in the media. While most terrorists and other assorted bad-guy types are not necessarily the sharpest knives in drawer, there are some that can be able to distill good information to some degree. Whether that degree is sufficient to save their hides is a matter open to debate, but that they can get some information that may have some pertinence is not. Not from the movie per se ...I think the big issue is on the media reports and not on the movie (which can be seen as an impressive recruiting tool for the most part).
As an aside, I wonder how the OTHER Tier 1 Asset thinks about all the attention DEVGRU has been receiving. By this I am talking about the Combat Applications Group, or CAG (known to most as Delta Force). DEVGRU has gotten series attention, even if the media is still using its old name, while the mention of CAG would be met by a 'what' and even using Delta Force would probably have the average person thinking it is some airline crew (and maybe older souls thinking of some poorly acted Chuck Norris flick from the '80s).
I would bet serious money that the folks over at CAG are 100% ok with their anonymity, and they know the only reason DEVGRU was used for these missions is primarily because Admiral McRaven used to be a Navy SEAL himself, and as most people would do when faced with a difficult mission, he selected a Tier 1 outfit that he knew quite well. I am certain if the Commander of SOC had been Army there is a good chance that the other Tier 1 outfit, CAG, would have been selected. All the same, DEVGRU and CAG are real world supermen, although one of them is far more visible than the other. For good or bad.
