The movie left out major details. The home and family support that Marcus had at the family ranch in Texas was heart warming.
As soon as news came down his unit was in trouble, his fathers ranch was overwhelmed with VIP's, high ranking Military brass from all branches, the Bushes came to support his parents, Wealthy local builders brought in trailers for people to camp out and await the news, local resteraunts sent over truckloads of food to feed the huge crowd of supporters, the Navy Chaplin flew in to pray with growing masses. Radio men set up direct SAT phones.
As grim details of the botched mission were starting to emerge, family and friends were losing hope, crying and praying, One of the Navy Admirals that flew in, pounded his fist and said, "A SEAL is not dead until you show me a body!" and that's an order!
I never read an account of such strong family and friends supporting a MIA. Those Texans know how to rally ! I guess it was to much conservative love for Hollywierd to document in the film.
