This looks inaccurate, too. Only because Installation 05 would be somewhere else besides the Orion Arm in the galaxy and Truth's ship managed to jump there. Now, granted Covenant ships and their slipspace drives are far more advanced than that of the UNSC. However, if an Assault Carrier can travel a fifth of the galaxy in the span of a month and it takes about a month for freighters to reach Harvest from Reach and given the fact that finding habitable planets is extremely rare, the distances would be much greater.
It seems pretty inaccurate to me too. Nonetheless, it is canon.
This was 20 years into the war. One very late first move.
How come UNSC turtled? How could they attack the Covenant? When your colonies are getting glassed each and every passing day and you're loosing ship after ship, fleet after fleet, how can you move on the offense when you have nothing to fight with? Did they abandon all the Outer Colonies? No, they didn't! Did they reunite all their fleets at Reach? No, they didn't! When the Fleet of Particular Justice arrived at Reach, they didn't even call back all of them; their armies were so scattered they managed to regroup only the 40% of them. Were those ships hiding or defending another planet or were they gathered at some strategic point, I don't know.
