just because the Pillar of autumn didn't carry battle rifles doesn't mean that none of the UNSC navy had them... remember the Pillar's assignment was to board an enemy ship and use it to capture a prophet... mabey an assault rifle made more sense for the up close environment like the inside of a covenant ship than a battle rifle did... also its larger ammo cap may have been preferred over the BR's 32 shots...
its the same deal with the pistol... why did they have HE pistols with scopes while the rest of the navy seems to be using standard pistol's... the reason that many of the stuff that was on the autumn is different from other UNSC ships is because of the nature of its mission.
I used to have an awesome signature that linked to my comic here...
too bad... goodbye any feeling of personalization on the HWF... 3 years of sig making for this website down the drain
