Undoubtedly Hollywood. Members equip their guns individually as they see fit for the given mission and so you would expect a wide variety of gear being used. Some do/will use Eotechs for CQB type situations, but you would not expect to see a consistent use of that sight and a consistent non-use of BUIS.
