Any member of the United States Military - regardless of branch of service or particular job - is subject to the lawful orders of those appointed over them. This is a part of their enlistment/commissioning oath and as such, they willingly and without reservation took this oath as their own. Consequently, Lt. Watada is subject to those orders, regardless of whether she agreed with them or not. Having Sean Penn come out on her side says it all - he is the epitomy of a traitorous sleaze, and anything he says is not worthy of even a mention. The Lieutenant should obey her orders and that is that.
