If I'm faced with a defensive R&D tech or an offensive R&D tech, I will always give precedence to the defensive tech first.
Getting those Barbed wire/Concrete Pillbox/Concrete dugouts as early as possible is my major R&D priority. Then Counter-Battery Fire.
This is for whatever side I play.
Of course there is pressure especially early game for the CP player to let offensive techs take precedence over defensive techs. This is a mistake.
If you look at WWI in the West the Germans conducted a mostly defensive strategy after the failure of the Schlieffen Plan, and apart from Verdun ( no one was thinking straight in my opinion ), and Michael in 1918 the Germans gave offensive priority in the East rather than the West .
Most CP players will not get to Paris in 1914, so the Western Front has to be turned into a giant fortress.
Wherever the enemy can attack on a three hex front must be evaluated in terms of its worth.
If you are gaining no strategic benefit from its occupation, or it is not to be used in future offensive ops, consider withdrawal.
And always maintain a strategic reserve.!!
Actually, that makes a lot of sense for Entente, now that I think about it, since Entente (or at least me) seems to be on defensive for at least 2 years. Maybe that is what I will do next game. This last game I lost to the overstack flow 34 error.
In your opinion, what does the AI do as it relates to research? Offensive?
