[ANSTHRLD] Primary Charge Group Help

[Brendan Haiduk]

I'm trying to conflict check:

Per pale sable and gules, in a fess a sword between two lions comabatant
argent.

In doing so, is the sword the primary charge group, or is the sword and
lions the primary charge group?  I know the sword has to be primary because
it lies across the filed division, but I don't know how to tell if the
lions are part of the primary or a secondary charge group.

Thanks,
