My question is if a bg sees TWO friendly battle groups break in the impact phase one of which was already fragmented does it test twice (once immediately and once at the end of the phase) or just once... And if it tests twice does it take the second normally or at a -1?"If a battle group must test for multiple breaks due to charges, or multiple breaks or lost commanders at the end of the phase, it only tests once but with a -1 adjustment..."
I am thinking twice, no modifier.
