If you have Heroes of the Nam, which combines Forgotten Heroes and Anzac Attack, you should have maps 1-5 and 8-9. Maps 6-7 are in Heroes of the Falkland but I strongly doubt you need them for any scenario from Pledge of Honor (don't have this one with me at this time). You should also have the third Mk V Counter. If you only have Forgotten Heroes, you will not be able to make full use of Pledge of Honor
