Resident Evil: Afterlife (2010)

Continuity mistake: When Luther ducks to avoid getting hit by Alice's plane, his gun falls out of his pants. He then picks it up again just before he runs off to clear the roof. But in the shot where Angel runs away, his gun is still lying in the middle of the "E." (00:30:20)

Alice: Day 6,1800 hours, Los Angeles. No signs of life, not even the undead. They must have burned with the city. But what about the rest?

Trivia: The only movie out of the first five films to not include an extreme closeup of Alice's eye opening as she wakes up near the beginning. The shot had become a trademark of the series, and was re-used again in the subsequent fifth film.

Question: I've seen the movie several times now but I still don't know the answer to this: in the beginning of the movie, who kills the two Japanese snipers - zombies or some clones of Alice?
