I know for a fact that PLs cant sign off an Article 15. They can recommend it, but they can't sign off on it. A 1LT should only be put in command of a unit of 71 or less according to fm 6-22... so I could see that maybe in some bullshit unit/detachment, or as a stand in for a CPT or above, but it certainly wouldnt be regular protocol
