One detail, without going into my own background: the night shots could be easier, since both the people and those waters are likely to be calmer at night (less wind-driven chop among other considerations). No debate on the raw amazing skill of the SEALs, but they might have preferred the night shot to a daytime shot (although personally I would have preferred the night shot on the first night).
Apparently the swells had gotten worse during the day - the shots were taken around nautical twilight, so the swells had apparently not had a chance to diminish. But I would have preferred the first viable shot been taken.
