These terms are used and misused quite a lot in my life atm: planning business direction at work and spend too much time watching board game videos on Youtube at home. The misuse is mostly when they’re used interchangeably and there are plenty of pithy aphorisms to explain the difference like:

Strategy is undertaken before the battle. Tactics are implemented during battle.

Or:

Strategy is the what. Tactics is the how.

But by far my favourite way to think about it takes me back to the early noughties when the only time I/we would use the word tactical was in reference to ‘going tactical’:

If the strategic aim on a night out was to make it to Sugar for the £1 pound vodbulls and I was too pissed too early I’d go for a tactical chunder to help sober me up.
