Stephane,
Tell me the truth...
Are you a professional Vietnam researcher??
LOL
With the progress that Boonierat is making on the historical research, soon we will enter to one of the most critical activities for the campaign...
We will choose/connect the battles/operations/locations with the evolution of the core army and we will create the Theatres of Operations.
The trick is to make a smooth evolution from smaller (core force) missions to a progressive increase.
In case of "MUST HAVE" big battle in early stages we should use AUX forces.
cheers,
Pyros
