http://guides.ign.com/guides/734817/page_2.html it is a guied to all of halo 3 (copy and paste)
First of all reach is not an expansion to halo 3, its completely different and takes place before any of the halo games, And second the camouflage last about 30 - 35 seconds
It is some were in the second level ,but if you what to know the exact spot look on youtube.

On the contrary it was. It is seen in the second to last level called Cortana. in this level you must recapture Cortana and blow up High Charity; The flood infested Covenant home world.
