You get the rewards for winning the battle which happens automatically when you destroy the Main Body of the Acient Sentinel.

In other words: You can just kill its main body. Most players find it easier to kill at least the Ranged Weapon System (right arm, left for players) though, as it can deal a lot of damage.
