The tent is only accessible for a few seconds while the Courier receives the Veni, Vidi, Vici quest from Legate Lanius. The inside consists of a center table where maps of Hoover Dam lie for what seems to be strategical purposes, as well as two Praetorian guards, many dead NCR troopers, and slaves. There is also a live female slave, who is tied up, in the corner of the tent. If the player character is sent to kill Legate Lanius in one of the final quests, then the tent door will be locked with no way to enter.
There is yao guai meat on a table in the Legate's tent. This is the only piece found in the base game.
The Legate's war tent appears only in Fallout: New Vegas.
