As for more detail, is there anything specific you’re looking for? I’m afraid breakdowns by unit are difficult to add because of how many entries are involved right now. The Romans have 12 types of infantry alone involved in combat because of the different generations. Maybe one of the tools can provide automated analysis from the database?
I would never suggest taking such a burden on yourself or any author. Some people will do this anyways and have fun, mad though they may be, but for most this is too much grognarding I think. Again, it bears repeating that the current approach is entirely fine and good if that is how you prefer to approach it.
However from the narrative side, if you wanted to pursue it, highlighting a specific formation or commander and adding a narrative (which may or may not be closely tied to the actual game events) can be a fun way to add narrative depth. Highlighting a specific event (in-game or imagined) is another approach, for example the attack/counterattack which led to destruction of most of the Sword's remaining tank forces on Day 4 would be ripe for expansion, as a significant tank battle a la Prokhorovka for example.
Of course, I must emphasize that you should do absolutely nothing on my account.
As the author the story is entirely yours, and as readers we enjoy it in whatever form it takes. All I offer are ideas to stimulate the imagination. Also sometimes I make bad jokes.
