User blog comment:MilitaryBrat/Master Chief vs Xenomorphs/@comment-4749025-20120203224623

1. I'm using the Aliens from the comics/books there are two types of aliens movie versions and comic versions, Comic versions are bullet proof and are in 24 ton range (READ ALIEN HIVE!) that's why you never see it in the movies >_> I'm using the BOOK VERSIONS! and since the OP did not specify I'm going by their most powerful incarnation which is the Book version

2. Colonial Marines had range advantages and still died, and still you did not prove his weaponry can pierce the hide of a Xenomorph warrior I'm being generous enough to say it can be pierced by Master Chief inferior weapons.
