Tactics? What's that...
The class in VA basically just covers firearm handling safety, how to shoot at the range, a little history, differences in firearms and cartridges...then shooting various guns at the range for an hour. A couple people in my 8-person class had never fired a gun before, and here they were getting their CHP.
I really think it depends on the instructor/company. Some go a step further and include information about implications of using a firearm for defense, so ask around for a good class.
