I guess I was just looking for an easy way to be able to understand and tell in game when I can expect a beaten down unit to come back up to strength. This is just so I can guess when I will be able to use the unit again. Doesn't this seem like something you need to know? Or, maybe I am confused?
Sorry...there isn't an easy way to know with any specificity. The division of the replacements among units is somewhat randomized, and given a dearth of equipment in the in hand pool, it can take quite a while, especially as the battle continues to make changes in the unit call outs over the course of the game. Estimating your re-supply rate is much easier, something that you generally have more control over, and often accomplishes much the same thing in terms of actual battlefield performance.
To really find out more about the specifics of any particular scenario, you would have to dive under the hood, and load the game into the scenario editor, to review the replacement priorities set for the entire OOB, and make some guesstimates based on the specifics of your game's attrition rates, and the total number of replacements going into the pool. Not recommended for beginners...
