1) Set the core points you want before generating the campaign in the preferences screen.
2) There really is no need for a tactics page (there is no "strategy" in this game as the level is too low, it is not even at the operational level
. There is a sticky with links to the US Army tactical field manuals on the main page, as well as the tactical help section of the manual, and tactical threads are welcomed on the AAR forum as well. (See the one on use of air mobile and panzergrenadiers in there for example).
I would recommend FM 71-23 as a starter
http://www.globalsecurity.org/milita...rmy/fm/71-123/
Read the Coy and Bn parts, ignoring BDE, and also look at the "threat" sections which describe OPFOR approaches to tactics (i.e. Soviet-style).
3) If a beginner, then leaping into modern times, with its lehtality of kit is probably not the best idea. Try the early 1970's or so as a starter period.
