And if those individuals making the arrest are masked and refuse to identify themselves?

If you don't know or should have known that the individuals are law enforcement personnel authorized to use force against you, you probably have the legal right to defend yourself against the use of force or to try to evade being restrained (100% absolutely not legal advice!!).

If they tell you that they are law enforcement but refuse to identify themselves personally, I think you're going to get into a huge pile of trouble if you try to fight back or evade being taken into custody. Because then you're in a scenario where you know (or should have known, or could reasonably have concluded) that they are law enforcement - and then it's very very illegal for you to use force against them.
