If for example Rex does 2 movements in his activation does Tactical 1 trigger twice?

Does this text below give any explanation?

If an effect provides a unit with a free action without specifying a type of action, that unit may perform any action that it could normally perform. Performing that free action does not count against that unit’s two actions per activation, but is considered an action for the purposes of game effects and therefore does not allow a unit to perform the same non-move action more than once during its activation.

Thanks in advance.

Short answer is yes he will get 2 aim tokens.

Each time, after he performs a standard move he gains an aim token including his scout 1 move during deployment.

Also tactical is not an action at all, it’s an effect that occurs after a move action.
