For Culthrasa ;
YES !!, it's always a great idea to clear up the opening backlogs in equipment, however, you'll soon need to expand your production capacity ... so get it done EARLY ['36-37] to have at hand the "Slings and Arrows of Outragous Fortune" to drop on somebody else's head .
1] Almost all of my games have had a short, sharp SCW; which lasted 2-3 WEEKS tops, and it was OVER before I could send anybody there !
2] Most of the videos I've seen show later-game production screens with 45+ WF's of this or that in the pipelines, and "where do I want/need to put these 8 new WF's", {a thing of drooling ENVY} when you look at the date - August'43, of earlier . If you don't build those CF's now, you'll HAVE to build them later; to put WF's into place while going up to the next level of tanks, etc .
3] I don't know if this works in MP, but I refuse to send green troops to anything, much less than a fight . Regulars can take care of themselves, greens can't do a proper bar fight .
4] Absolutly agree that War Economy is essential; just be careful in picking a little twerp nation to stomp to get there .
5] Once a template is made, you can train a bunch of them in your training centers, OR you can promote units in the field on a 1-by-1 basis into the new template .
6] Producing equipment determines the use of manpower; 3 million men and only 10K rifles = a bad case of un-preparedness .
Oh !, my point about the eastern Volga River WF placements IS historically accurate .
