There were a few errors in Leatherneck and Victory Games attempted to correct them by including a page in the Paragraph/Mission Booklet. On page 20 is a Mission Card Corrections sheet, with the following directions:
These corrections should be cut out and pasted or taped to the appropriate Mission Cards, using the large hex letters as a guide for proper alignment. These changes effect:
Mission 11 Condition 1
Mission 12 Condition 4
Mission 12 Condition 5
Also included in the box is a Leatherneck Mission 11: Fields of Fire Condition 2 Replacement card. It includes Japanese movement not found on the original card included in the expansion.
Of note to the player is the fact this card can be overlooked - given the propensity that Victory Games had to place it underneath the flyer and catalog in the bottom of the box.
