He did NOT survive!
After you found the Silent Cartographer and you reached the Stealth Elites on the top of the structure, use the Warthog (if you still have it) and take it to the LZ again. The Marines on the LZ that had the attack did not survive it and the Covenant must have also ditched the LZ. If you took Waller with you on the Warthogs at the beginning of the level, there is a small chance he survived the battle. Don't believe me? Play the game yourself! (Waller MAY have a chance of surviving if you took him on a Warthog, but in the books, Waller could be refered as KIA) --Blemo 04:13, 12 April 2007 (UTC)
