Keren's not in North Africa though...
Lol, we have been through this before Lightning. I know where Keren is, but for the sake of simplicity and association with our existing theatres, it is best to relate the Battle of Keren to our existing North African campaign maps. (unless you want to promise a NEW East African theatre, and you surely do not)
For those who wish to know, Keren is an ancient province of the Kingdom of Ethiopia (During WW2 it was still Ethiopian, under the control of the Italian's, but is now part of Eritrea).
