An additional concern is the type of units selected within each branch of service. For land offensives, HQ's and armor are needed. For land defense, HQ's, militia, territorials, and garrisons are very good, with infantry and AT a close second. Paratroops and marines are excellent for attacking, if their special capabilities are needed. What I am postulating here is that the strategic objectives (defend Great Britain versus invade continental Europe) dictate which types of land units are selected for construction with the build points allocated to land units.
I'd add that unless the CW is in the ropes, building the MAR, PARA, ENG, and newly available HQ is a must do for the CW.
The CW must become highly aggressive very soon, and so should build all the units that make it offensive at first opportunity.
I'd add, I don't remember if I've already said this, that I think that building 2 AMPH, one first cycle in S/O, and one first cylce in N/D 39 is a must do for CW IMHO.
More, as Composer said in his good production post.
In case votes count for anything here...I completely agree!
(Although I still believe that CW must also remember to garrison the pacific and keep in mind that its more important to keep Suez, Malta etc than to take Tripoli or East Afrika in 40 )
