Stupid question coming up....
Characteristics p205 - Expendables.  1. Expendables fight normally but any S result in charge combat converts to a Skull result.
Does this refer to the enemy unit being hit, or the expendable unit?

Think its the expendable attack dice so therefore would apply to damage done to the enemy, I guess since their limited life span is short they cause chaos for a short period.

Pretty sure most of my best units seem to have the expendable characteristic without it being recorded....

Thanks for that. Most of my units seem to be expendable when I get stuck in!
