Went to see the movie Act Of Valor today; I encourage all to see this film in a cinema if at all possible.
A reasonably straightforward telling of an entirely plausible-seeming (to me, at least) threat with all of the to-be-expected combat action people have come to associate with SEALS and Special Forces generally. HALO jumps, air insertion of SEAL Tactical Assault Boats, the STAB boats in riverine action, it's all included and beautifully filmed to convey both an accurate image as well as the impact caused. I found the commo discipline as well as the shooting under stress and movement (specifically, the reloading and communicating between fellow teammates) to add an additional layer of suspension of disbelief.
I suppose that the predictable-seeming plot point that occurs towards the end of the film (no spoilers here - spend the money for this one, it's worth it) is more than justified by the final on-screen scene. It stops being a screen writers dodge when you start to count up all the names of those who actually did just that sort of thing at some point during these last ten years of war.
Go see this movie; buy a copy when it becomes available on DVD, you will want to watch it more than once, I promise. And if you don't have to hold back the tears just a little at the end, I don't want to know you.
Update: Via Glen Reynolds, this is no surprise.
