Since I couldn't exactly find the description of Strategy I just asked around a Fate discord server and they gave me that description.

I don't know where the hell they got that from, but the actual description is more like:

[i]The capacity to grasp victory before the battle begins, using the broader purviews of such things as diplomacy and logistics. 
In her prior life, Nobunaga's surprise attack at the Battle of Okehazama was successful, but this was merely a fluke. It is said that in her lifetime, this fluke was the only battle that turned strategic defeat into tactical victory, but even then was a desperate fight. To this day, she reflects on this battle.[/i]

Hasty translation on my part so some nuance might be missed, but suffice to say it's more related to preparation for the battle than Military Tactics, which is for the battle itself.
