You could certainly do that digitally no prob, but for an actual tabletop game... i dunno, feels too sacreligious to me to just straight up turn chess into a tactics combat game, lol.

I like the idea of a simple rule set that is easy enough to keep track of, but also allows a wide variety of possible strategies within it.

I think keeping the ... stamina pool or whatever, shared and common to the player, well it simplifies an ongoing irl game's tabulation as compared to keeping track of all units, and its also more like...

You are the commander, and you are managing the logistics of a whole army.

This is why I couldn't settle on the terminology... maybe 'command points' would be a better way to phrase it.
