The terms "strategy" and "tactics" are commonly used in discipline of bussiness.

In business terms, you play your tactics to reach your goal - which is defined briefly as your strategy.

Strategy is a general purpose - say, "We will grow by increasing our market share by %10 by the end of this year"

And when you increase your promotion expenditures or buy some smaller company in the market to enlarge your market share or any other "tricks" to reach your strategy defined, you are counted to be applying tactics.

And I bet that conquering Istanbul in order to gain geographical, religious and psychologic advantage was the strategy of Ottomans in their growing times. And building of Anadolu Hisari (the fortress built on the Anatolian Side before the conquest - I do not know how you call it) to control the sea around Istanbul was a tactic to achieve the strategy.

So I may mention the famous Turan (or Hilal- translated as Crescent ) formation in which the frontmen of the Turkish army used to make a fake setback in order to persuade the opposing army to follow them, while the mounted wings of the army were covering the rivals around and from the back. The end was a total demolition of the caged opposing army.

And this is the Turan tactic, I must say.
