I believe that it will include Feds (BATF, FBI, DEA, Marshalls, possibly IRS and others). You're right; that won't be enough. I believe that the State Police, county police, and local police along with some sheriffs will be involved. In some states, National Guard may be involved, as well. For 'riot control', you see. Not all personnel in these entities will go along, and there may be serious armed internal dissent, particularly in local police and national guard. IMO.
Additionally, they will not be out there "violating citizens' sacred Constitutional Rights. They'll be arresting 'scofflaws', breaking up "terrorist cells", stopping "violent extremists", etc. There will be a concerted propaganda campaign from Big Media and Big Government to paint all gun-onwers this way. That campaign has already begun. We are currently in a war of words against the tyrants and rapist-enablers in Big Media and Big Government. The battlefield is in our neighbours' minds. Pass up no opportunity to fight the good fight.

Homeland Security has already labeled preppers as possible domestic terrorists. That is written in their documents for everyone to see.
