Well the US military (from whom the term comes) doesn't seem to understand the difference between tactics and strategy (it defines the difference in terms of the number of people involved). I understand tactics to be about execution, strategy about setting and changing goals, but if you search for discussions on the subject you'll find a wide and confusing range of opinions. Given that the first use of a "tactical" nuclear weapon would change the nature of any war, they're a rather strange idea (and in practice, tactical nuclear weapons were phased out because of this). Strategic nuclear weapons changed the rules of warfare, redefining the goals that could realistically be chosen -- one of the few unambiguously correct uses of the word "strategy" IMO.
