I have prepped a bunch of stuff for the table, if you follow that listing on here. Much of it is 15mm Deutsches Afrika Korp (DAK) for Flames of War v. 4. Of course, the same minis can be used for earlier versions as well, though possibly in different numbers per unit.
I will soon have a decent DAK selection for North African warfare. That would include a small infantry company, two platoons of Panzer IIIs, a platoon of Panzer IVs, a battery of Lorraine Schlepper 15cm guns, a Panzer II OP, and a pair of the dreaded Flak 36 8.8cm guns. I want to add a pair of Stukas, enlarge my infantry sections, and build a second pair of Flak 36s. I may go ahead and get a pair of Tiger IEs from Schwere Panzerabteilung 501, too, but I am wavering on that. There were only like a dozen in all of Africa, after all. I own a fair number of unpainted halftrack transports, and a Kradschutzen motorcycle platoon for version 3.0, but I don't think they have rules for them in version 4. Maybe upgrade cards?
I also took a look at what I already have for my British 8th Army forces to oppose the Huns. My infantry is solid - I have Indian troops. I have a section of India Pattern recon vehicles, too. For heavy stuff, there is a battery of 4x 25-pounders, a Honey OP tank, some Grants, some Crusaders, and a pair of Hurricanes. I have some 2-pdr and 6-pdr portees, but I have to look at how the game treats those in 4th Edition. I think there is an upgrade card for it, just like there is one for Indian infantry.
Other than Flames of War stuff, I have a variety pack of 28mm stuff. That's basically stuff that has been sitting about, and I can use them as relaxation from the eyestrain of painting 15mm. That's getting harder these days.
