I really enjoyed your AAR. The style was perfect. I noticed that the father was writing to his son. Since the son was also in the army, it made sense that the letters should discuss the battles the father was involved in.
I may use that format if I ever decide to do an AAR of my own.
The map size you chose may be a little small for me, but I find that with small-ish maps I get to know my troops better. It's easier to understand the overall battle. Plus, on larger maps it can take a long, long time to complete a turn, with so many squads to move and so many op-fires to resolve.
I love the large maps that come with the game and the ones being made and posted here, but playing with them just takes too much time.
