Sarah aimed around with her sniper rifle, and the pelican took off again. Mary, who had the gun's camera linked to her helmet, looked around. She saw a cluster of some greyish coloured creatures with some sort of mask on them as well as a tank on their back. "There's some... Things, up ahead. I'm engaging." She began to fire at the cluster of enemies. She saw one that looked like either a bird that walked or a lizard with no tail walk from around a corner. It saw the UNSC forces and clicked on what seemed to be some kind of blue shield. Mary focuses fire on it, and takes it out. On the ground, Sarah opens up with her sniper rifle.
