[quote] 1. Is there an explanation as to why there is new UNSC hardware on the Forward Unto Dawn?[/quote] That is magic. Just like how the DMR was introduced in Reach and not the other games. It's just a game aspect, not something that needs to be over thought. [quote]2. How is it that human weapons, Tier 3 Technology, are so effective against Forerunner constructs, Tier 1 Technology?[/quote] After the war with the Covenant, Humanity progressed to a Tier 2 civilization as a result of all the technology that had gained from both the Covenant and Forerunner constructs, or close to Tier 2. This is similar though, because humanity was a Tier 3, while the Covenant with their weaponry made them a Tier 2, or close. Being on a higher tier doesn't make you invincible. Humanity fighting a Tier 0 Precursor, I would call BS, but at the same time, a lack of Precursors shows that even at Tier 0, they were not invincible. [quote]3. How is Chief's suit adapted for Armor Abilities?[/quote]Same answer as number one.
