“Move each of your armies up to 5 spaces. They can move into spaces matching this slot's terrain or lower, as well as water. During your turn, reduce the combat bonus provided by each reinforced control token by 1. [2 armies]”

I just want to make sure I understand this correctly. Does this apply to the bonus provided by adjacent reinforced control tokens? So unless the defender is China, then reinforced control tokens don’t provide any defense against this card or is the TOTAL combat value reduced by 1?
