I'm playing a game on Vassal, where for the purposes of an objective myself and another player have been trading planets this round. It is in both our interests for one of the tactical actions to involve a "surrender".
From the FAQ: (page 4)
" Q: Can you voluntarily reduce number of rolled dices in space
battle, bombardment, PDS fire etc?
A: No. You must either roll all of the dice or none of them."
This is confusing me now, I always read this as a person always has the choice to roll no combat dice, effectively surrendering. Problem is some others disagree, can anyone help clear this up?
