On what grounds (besides searching for drugs, contraband, stolen articles, recovering equipment/clothing) can a soldier's army locker be opened? If the soldier is not in attendance is their some type of formal protocol informing the soldier after the fact declaring that his locker has been opened and the reasons why? Does this have to be in writing or officially recorded somewhere? Who has the authority to allow a soldier's locker to be opened? Is there an army reference document that details this type of specific issue?
