We have been using this quick and easy rule for testing, and so far it works fantastically well. On top of it all, this method matches perfectly with the changes made to rolling the six command dice by Elite troops as explained in the Errata and FAQ. See the “Elite Troops and the Sixth Command Dice” for more details.Green Troops and Four Command Dice
When rolling four command dice for green troops, the player rolls five dice instead. However, one of the command dice should be a distinct and different color to the others rolled. So, for example, you might roll four white dice and one red one. If the differently colored die, red in our example, rolls a 1, 2, 3, 4 or 5, it is ignored. If the red die rolls a 6, then this is treated as such and counts towards the number of 6s rolled for the Phase Sequence Rolls (see 6.1 on page 25).
This will mathematically balance the odds of rolling 6s on the dice for the different forces (Green, Regular, Elite). In short, the actual chances of rolling 6s with four dice plus one colored die for Green troops, five dice for Regular troops, or five dice plus one colored die for Elite troops are now effectively the same.
This does not affect any of the point values for forces.
We have not tried the idea of counting both 5's and 6's so that Green platoons can generate CoC dice at the same rate as Regular platoons. The main (and critical) reason for this is because there is a mathematical difference between Regulars and Elite troops at generating CoC dice, so there should also be a mathematical difference between Regulars and Green troops at generating CoC dice as well.
We will like to test our our new idea even more before coming to any final conclusions, but everyone is already thinking its a sure thing and should be included in the game. What we are wondering about is why this has not already been implemented when the “Elite Troops and the Sixth Command Dice” rule was added to the Errata and FAQ. It seems so obvious and logical that its almost a mystery. This is why we are very curious what Richard Clarke (designer of CoC) has to say about our "Green Troops and Four Command Dice" idea. We are hoping that he likes it a lot. So much so that he makes it official.
Which color die to use?
Some CoC players have jokingly suggested using a green colored die to show that the command dice being rolled are for Green Troops. This is a creative idea, but not mandatory or necessary.
