While Broken Lines looks like a fine tactics game, the "alternate history" label is what keeps me from being too interested ATM.
Although Close Combat is great, yeah trying to stay turn-based. ;)

Combat Mission is a bit closer but not quite as team / squad specific as I'd like... and the cost-of-entry to the newer titles is prohibitive.

Erm... since when? You can download it from their store.

What do mean here by 'RPG'? I would not classify either Close Combat or Team Assault as such.

The first time I loaded the game page on Matrix' website it only seemed to allow physical delivery.

From Wargamer:

Back to that ?Force Builder?; it?s an editor that can be launched from within game but it will minimize the game in order to run it. I think this is the best part of the whole game. Players can create squads from scratch here, creating their names, adding a description, and a custom amount of soldiers. The soldiers can be assigned a rank ranging from Private to Major, be given a firearm from a large array of options?ranging from sidearms to heavy machineguns?, and an equipment pack. Equipment packs include medic kits, demolition charges, mine laying gear, and extra munitions. Up to five squads can be produced and each squad can hold up to eight men. These customized squads can then be saved and loaded within the game so they can fight to the death.

While not a traditional RPG campaign where you define specific characteristics over time, you certainly name, create, arm, outfit, and rank your team. IMO that would seem the most basic of role-playing systems. Granted, I understand these basic systems don't make this an actual RPG.

Would I rather have a campaign with both turn-based tactical elements and a full-fledged RPG system? Certainly, but after seeing how little is out there is war gaming, I'll take what I can get ATM.

With that said...

Burden of Command looks to be very much what I'd hoped with RPG elements, but I'm not 100% sold on hex-based grid games where you're positioning entire platoons, squads, or teams instead of individual troops. Still, I'm very interested in the game and have been watching it since first announced.
