Operation Difficulty and Rewards
The difficulty of an operation for the task force is based upon the total experience points (not victory points) of all the players combined. The reward for the operation is also scaled according to experience points. A high level player will make the operation harder for the task force, and will receive a greater reward. But he won’t be pulling his weight if he is using troops, gunboat weapons, and landing craft that are not appropriate for his experience points level.
Not all players upgrade troops, gunboat weapons, and landing craft immediately, so a 3 level buffer is allowed to get up to an acceptable level.
