@crockett36 I’m also going to have to call ‘foul’ on the submarine spam. The amount of subs is limited by the number of pieces in the game (not chips). Since only six sub groups are allowed on the board at any one time, you’ll have to combine one of those subs with another.
Reference: page 7, center column under “plastic chips”.
The official Q&A also back this up:
“The number of playing pieces is a limit on how many forces can be in play. No one, for example, can have more than three bomber forces, or more than two carrier groups. The only exception to this absolute limit is chips.”
