Currently, ranged units that COULD fire or where maybe one or two icons are firing don't get the ZZZ marker despite them not being productive in battle. Valuable battle time is burned thinking they're being productive while you micro other units then you realize none of their ammo has been used and they're sitting around not doing anything.
If there was an icon to let you know that less than 50% of a ranged unit (or whatever % is deemed appropriate) is firing, that would be quite helpful, particularly in multiplayer and legendary / battle realism mode where you can't sit and watch to make sure the ranged units are actually firing. Given the not always clear site lines, this would be a great visual queue that would help productivity, enjoyment, realism, and accessibility.
