In your scenario (2 reg commands only) you would roll 2 dice of the same colour (to represent the regular commands - assuming they are on table)
and 2 other dice each a different colour
so you roll 2 white dice 1 red and 1 blue
they land white dice 3, 5 red 6 blue 2
The command with the highest allocation gets 5
The command with the next highest gets 3
The red dice is discarded as it is a dummy and rolled a 6
next turn roll the 2 white dice and the blue
Alternatively - if there is likely to be no weather impact from dice eg no risk of rain wind etc and its pretty obvious all your points are visible and on table then just roll the 2 white dice (and say Sorry Norman when you do
