Optix,
1) Yes...all French 2TAF airbases should be removed.
2) No, you do not need to remove French bases by Achim which have already been released. This airbase pack simply includes ALL of the French airbases, the majority of which are new. Leaving his older French bases in will not affect them in any way, they will simply be overwritten.
Does that help?
Yes! Thanks for the lightning reply, Rami! I shall proceed!!
