Playing through the base campaign a time or two before buying the grand campaign, and then really forgetting what the sun looks like.
Custom settings, basically Colonel with a 5% prestige boost to me and 10% to the enemy, plus an extra turn. Farming for the new player until I get the hang of the differences between this and PG Forever.
I have taken the "green"(from the manual tree) campaign path and am now at the USA East scenario.
Saved at "pre-buy" with 8900 prestige. Can always go back and buy again. After restoration, balanced upgrades, and over-strength to 11-13, I am at 2646 prestige, and am also at a crossroads of options.
Still have the three core unit slots that the scenario gives me. Help me fill them with the 2600 and change that I have left please.

Here is my current Order Of Battle - I subscribe to the 2/2/2 divisional pattern. 2 tank, 2 inf, 2 art, plus attachments, per divisional formation, as campaign progresses. All INF units are 43. Gebirajäger are called Mtn and Grenadier are called Hvy Wpn, so I do not have to spell in German.
1st Div -
1x Pioneer
1x Hvy Wpn
1x Panther G
1x Tiger II(w/+2 move)
1x 210mm art
1x Hummel
1x 233 8Rad
1x Elephant
2nd Div -
1x Pioneer
1x Hvy Wpn
1x Panther G
1x Tiger I(w/+1 move)
1x 210mm Art
1x Hummel
1x 233 8Rad
1x Elephant
3rd Div -
1x Pioneer
1x Mtn(no transport-nimble li'l b@sterds)
1x Panther G(w/+2 spot/semi-recon)
1x Tiger I(w/+1 move)
1x 210mm Art
1x Hummel
There is a new(only +1 overstrength) core Pioneer that can be assigned to wherever they need to go. Only unit with the new halftracks(8 move).
Air Power OOB is...
3x FW 190A
3x ME 262A
2x Ju 87D
2x ME 410A
1x He 177A
1x E555I(good gawd I couldn't pass up those numbers, but the price made me squeal)
There are a plethora of other leaders that make my force quite formidable in the combinations I have placed them in... I just posted the relevant ones for tank movement and spotting.
The Elephants are semi-new as well, with only +1 and no leaders. I am hoping for movement leaders this battle.
All six artillery are maxxed at 13, recons as well. I prefer the movement and ammo of the Hummel over the protection of the 38(t). All other units are at least 11, and usually at least one under what they could be if I had the prestige. If my Level bombers were at 14 and 15 instead of 12 and 13 it would be a lot better at sea. I don't want to talk about what the E555 overstrengths cost.

So there you have it.
My thoughts... According to the campaign tree, I have two marginals to farm before I have to get the decisive at the west coast. If I needed decisive victories then I would buy three Paras and drop them down south, while burning the rest on upgrades and overstrength.
I want the rail gun. I want it I want it I want it.

The price of the really sweet toys will limit my purchase ability, to two nice ones and one para or some such. Mediocre units will probably melt under what surely awaits me in the next three missions. Especially being XP-poor, as any new unit will be.
All I have to go on is what I have read in the AARs re: what I am facing.
What say ye? Three slots. 2600 prestige. Existing core force is sweet but could be sweeter.
Saved at mid-buy, and taking a break. Maybe I will go buy the grand campaign for when I finish this one.
Thank you for your attention, and may your artillery never fall short.
