Wulfir and Suhir,
thanks again for your input and comments. It does sound like a rather daunting task. In lieu of creating an entire Congolese OOB for the entire history of modern Congo (ie from 1960 on to today), what I might do is to create a couple of scenarios that cover some key battles in the country in the period 1960-1968, concentrating on the period 1964-65. This will likely mean taking various red and green OOB's for that period and tweaking accordingly (with the possibility of adding a Congolese flag if it can be done).
If Wulfir is referring to the siege of Jadotville, it is a battle both my friend (the historian and scenario designer) and I would like to ultimately do for SP MBT. For those who do not know about this battle, please read up on it. It has an epic quality to it. I hold the Irish troops who fought there in extremely high esteem!
