PROTECTRON PARADE Scenario: Deatchlaw Objective

The rules say “If you have a Deathclaw, place it in the center. It’ll use the Solo Rules and will treat the objective as Defend trunk with the trunk as the subject.”

The problem is that Deatchlaw AI matrix doesn’t have objective, only Attack and Flee.

So how should I control the Deathclaw, use only one AI decision - Defend trunk, not rolling the AI die?
