When I hear 'squad based' I kinda like to see a handful of S Q U A D S!!! damn it. Not battalions of troops at the squad level

The best Steel Panthers experiences I have had, were mainly in Mega Campaign Screaming Eagles. You got a few squads, they were dropped onto the map and you had to make something of an entirely unplannable mess

Now some of the other Mega Campaigns are just as great. But the opening assault in Lost Victories is a sea of troops doing a river crossing . Oh boy I love cramming scores and scores of squads into a meat grinder. It's about the same with Watchtower and marines hitting the beach. In the desert, well it is a lot of vehicles and a lot of desert and a lot of ground to cover to close in with the Tommies. But Screaming Eagles was always a handful of troops and a smaller looking map and more tension.
Sometimes ASL gets it right and sometimes not. The very FIRST scenario from Squad Leader is a half of a board. And I love playing it. Fast forward many years later and ASL gives you historical module Red Barricades and a large map and massive sums of squads slugging it out in the rubble of Stalingrad. I generally prefer ASL to stick to 1 or 2 board settings and very limited forces.
Ideally I want a game to recreate THAT level of play and more or less you get that with Battle Academy. Which is why BA has done so damned well. Well I call it doing damned well to have sponsored the creation of 3 add on purchases so far and I see nothing to prevent more other than converting over to BA 2 which is fine with me.
I just miss my hexes

There's room for Panzer Blitz/Leader scale of action with is fairly close to Panzer Corps but not quite. I'd say PanzerBlitz/Leader is closer to Panzer Corps operational scope than it is to the squad tactical scale of BA and ASL. PanzerBlitz/Leader would be only a couple of cities at most and not quite as much terrain. Likely th difference of it being a company commander at most and not a regimental commander.
I have John Tiller's Campaign series, and the only fault I have with it, is the program is not 100% cooperative with today's hardware and OS environment. It works, but it is also showing it's age.
The only trouble with literal ports of board games into electronic gaming, is the turn sequence structure generally expects a human to be dealing with an interlocked sequence of moves and counter moves by the opposition that often will greatly tax an AI design. Hey if it was so easy, we'd have had World in Flames a few years ago, and Lock and Load would not have taken so long to get to where it is currently.
I won't be breathing the day they get ASL made into a board game and not a tool known as VASL. Because computer AI just isn't that good yet and isn't any where close either.
