User blog comment:J80Kar/UNSC vs The Holy Britannian Empire/@comment-5232784-20120823005133

That is waaaaay too many weapons to research and subsequently figure out which is better. However, if memory serves me correct, the UNSC is in the Halo universe, and the timeframe of that game is the 26th century. The Holy Britannian Empire (a really cool alternate history idea) is dated to the early 21rst century: a span of 500 years. In our timeline it would be like modern US army Rangers fighting Knights from 1512 AD. Technology and time make the difference, and te first guns made (hand cannons, Arquebuses, etc) are nothing compared to M16s. Can you imagine the deadly force weapons will have in 500 years? Given this, I see no other conclusion then that the UNSC will easily trump the Britannians, due to technological edge alone.

UNSC all the way
