The difference between a regular cop and a SWAT officer is that a SWAT officer has more training. And more armor.

Sometimes, the SWAT officer performs the duties of a regular cop. I happen to "know" a local sheriff's deputy who does. I guess it all depends on the department's policy.
One more thing, in most areas SWAT is not called for home invasions. What generally happens is a unit with a police dog is used, police stay outside and allow the dog to do the core work.
