Yes, there's not a hard black line you can draw between military and tactical. Military firearms, broadly speaking, are those that are designed for military use. They would include large-calibre armaments—grenade launchers, rocket launchers, etc.—the types of firearms that are mentioned in clause 95, I believe. The military firearms would also include fully automatic firearms. Military use would also include what I would loosely call tactical firearms. These would be firearms that are not fully automatic, but which fulfill a tactical role on the battlefield, such as sniping and other specialty purposes.
The term “tactical” is often associated with police and security agencies that are not permitted to use fully automatic firearms, but use firearms that are similar in nature, except for the automatic fire.
