 PLOT: During the scene in the watchtower when the team are preparing  for the next fight with the baboons, Brodie tells everyone not to  shoot unless they get a kill shot because they are low on  ammunition. In the ensuing gunfight all the team fire at the walls  without getting kill shots and only killing a few baboons, because  of this they have run out of ammo and cannot fight the next wave  easily. If the team followed Brodies advice they would probably have  had enough ammunition to fight all of the baboons.
