Jun is a sniper. They can be icognito as long as they want. What I think is that he took Dot and did some inside covenant reconnaissance and Dot took Jun's info and sent it to Cortana. Thats how cortana knows so much about Forerunner structures and other tid bits like how Cortana knew where the marines where help up in High Charity in Halo 2
First, toward a post acouple before this one THAT IS NOT JUN'S BODY! It is a normal marine. You need to look more carefully at the armor and not glance and assume. Spartan armor types are based on alot of Marine and Army armor designes, so it is easy to miss-identify.
as far as the quote above, if you played thru Reach, it is rather obvious how Cortana got the Forrunner info. She was derived from Forerunner tech on Reach. That installation N6 gets her from is a Forerunner database.
As far as the OP question. Nothing in the game indicates Jun died. It is assumed Halsey lived, and according to the books there were other survivors from Reach. In fact, in game they mention that the continent they are on is overrun, but they are implying that the other continents are not as bad off. The base Halsey and Jun go to appears to be on another continent where they then catch a ship off planet, as far as the game implies.
Either that, or Jun had to kill Halsey during a covy attack and died himself, but I think that would be mentioned at some point.
