If you have a unit of soldiers, the senior officer is in command of the rest, and has authority over them. But how do you express the reverse relationship, i.e. the soldiers are <in ???> of the officer, and they have <???> to/under him?

Subordinate is almost right, but it's an adjective and I'm looking for a noun, or maybe a verb. The sentence I want to write is analogous to "Captain Smith claimed authority over the operation."; something like "B Company claimed ?subordinatality? to Major Reisman."

EDIT: Another example sentence could be "Lucius Malfoy ordered Dobby to come with him, but Dobby denied having ?subordinatality? to the Malfoys."
