Just so you know, there are a few of us who play SB as a wargame. I play from external, map, and sometimes from the commanders position. I have been playing for years and never sat inside the turret or in the gunner's position. 10 years ago, it was almost impossible to do that, but eSims has added a number of features to make it easier to command larger unit scenarios as a wargame. The key is to know the tactics, formation, and route setting systems.
I have played Combat Mission since the Bigtime Software days. Haven't truly played it in almost four years since I really started playing SB more. btw, also a big CMO player.
