At 34:14, oil minister Reale is reloading his shotgun with visibly empty shells.
Early in the episode, Neil Krinsman tells Colonel Tom Ryan that Congressman Bruce Gelber served in the US Marines and because of that does not like Special Operations. Later Congressman Gelber tells Colonel Ryan that he is a soldier. A US Marine would never make the mistake of confusing the term "soldier" with "marine" They are distinct labels meant for their respective branches, the same as an airman or a seaman.
