🗺️ 作 (make) + 戦 (war) = the plan you make before a battle
作 means make or create, and 戦 means war or battle. A 作戦 is the plan you make before a fight, so it covers both tactics and strategy.
作 — person radical 亻 + 乍
作 combines the person radical 亻 with 乍, which originally depicted a sudden action or making something. The character means 'to do, make, or create,' with 亻 indicating human activity and 乍 supplying the sound. Over time it broadened to cover works, deeds, and acting as something.
