The terms come from warfare....

Tactics are whats going on at the front, they are decision concerning taking immediate action and how to do so with the biggest advantage over the enemy, its your ability to adapt to whats going on at the moment and make the best call.

Strategy is whats going on behind the front, they are decision concerning the goals of a particular campaign, the targets, to take the capital, to destroy the enemies factories for production etc. Its concerned with the overall objectives and goals of the entire campaign, its your ability to plan for a long term objective and execute succesfully.

In warfare they will use the terms "tactical victory" and "strategic victory"... a "tactical victory" is not the same as a "strategic victory".... for example if you send a group of people to blow up a factory or take a town that is a crucial part of a campagin, but end up losing tons of men and resources compared to the enemy, then that is considered to be a tactical failure, but a strategic victory.

Also you here the terms; strategic bomber and tactical bomber... a strategic bomber is one that flies far beyond the enemy lines and bombs a factory... a tactical bomber is one that flies into the fray to support the action on the front.

Playing a game of risk would be a matter of strategy... moving armies and resources etc. Making a decision to flank a group of distracted enemies is a matter of tactics... setting your forces up in the moment to get a tactical advantage.

Its really a matter of the scale/scope of the decision. Tactics are here, now, immediate, adaptable, advantage, disadvantage...... Strategy is planning, future, objectives, goals, resources, marshalling, logistics........

A football coach making a schedule of who to play when is like a strategy, where as the play by play calls is a matter of tactics.

The terms apply to everyday life also, a tactical intelligence is the kind of intelligence that a battlefield tactician would have whereas a strategic intelligence is the kind of intelligence that a battlefield strategist would have.

**I should mentioned, I don't know if these terms are completely synonyms to establish socionics theories etc...
