The main changes about the mechanics of the game regard an enhanced fire power of artillery and a major combat capability of disrupted and fragmented units, to make them a bit more resilient on the battlefield.
About the armies we're using, the only real difference is that now:
- grenadiers have lost some of their morale and elan, being above average and not superior, while gaining 12 AP pts. instead of 10, to represent their employment in critical situation and the consequent tactical skill that generals recognized them,
- guards have retained only 10 AP pts. instead of 12, but now are the strongest unit in the game, also better than grenadiers.
