Questions about campaign play

[RVPERTVS]

After more than 2 years of playing around with SPMBT I�ve finally decided to move on to campaign play, which I started a couple days ago with the �Thunder in the Sinai� campaign. However there�s some info I�m missing that I haven�t been able to find in the game manual, that keeps me from knowing WTF I�m doing, here are my questions:

1.- Are the core points the maximum amount of formations I can buy?

2. - Does fixed core means the designer have set the maximum number of formations I can have?

3.- What factor determines the purchase points allocated?

4. - In the second battle I was given some mortars, atgm�s and artillery units I didn�t buy, are these units fixed to the scenario?

5. - What are the support points exactly for and how are they allocated? For the second battle I was given 1 support point which I couldn�t use since no unit cost that.

6.- What are the �repairs� I�m supposed to do between battles? (to damaged units?)

7. - I know from the manual how points are gained but, is there any practical difference between gaining purchase, support and repair points?

Thanks in advance
