I obviously don't know much but it seems stupid to not tell your team who they're going after. They would use that information to plan the breach and I'd suspect a good squad leader would demand to know before going in.
Or it maybe my memory is a bit faulty and what I remember is regarding the search warrant used by the police. (http://arstechnica.com/tech-policy/2012/06/mega-victory-kim-...) The article describe how police officers didn't know what they were looking for when executing the warrant. As the judge put it, the people executing the warrant "were not the investigating officers and had limited knowledge of the operation," despite being briefed before the raid went down.
If I do find the article, I will post it. Maybe its was in the court document.
