by State having the lead? If you are referrring to situations where there is no major US military operation then the Ambassador (not DOS) is in charge of ALL USG activity including military. In such a case, the US advisory role is usually small vis the El Salvador 55. But note that the 55 were military. and the the Country team included AID and USIS etc under the leadership of 3 extraordinary Ambassadors - Deane Hinton, Tom Pickering, and Ed Corr. Our research shows tht small is bettter -see SWORD Model.
