Maybe I am a bit late but due to work I could not write earlier. As a Swiss myself I would like to bring some points to mind that hopefully can still be changed:
1. Mapwise, the Gotthardpass-VP is one Province too far West, same for Basel. For the passability of the Alps, all three provinces, the one with the VP of Chur, the one West of it (Gotthardpass) and the one that contains the Gotthardpass at the moment (what would actually be the Simplonpass) are passable from north to south, so the nonpassable terrain in the center of switzerland is somewhat misleading. What would be more interesting and also somewhat more plausible is to close off the east-west axis for passability in the central alpine region. While theoretically passable, the passes from the gotthardpass to the east into grison and the west into wallis are even nowadays up to 6 months unpassable.
So I suggest to move the Gotthardpass VP and change the passability in the alps to have three north-south corridors:
1. Lugano-Chur and further north (follow the railway), which is the san bernardino pass route. Please remove the railway from lugano to chur (there is no railway there, not even now), the railway goes to the northern ticino province and then through the (moved) gotthard VP to Zürich
2. Northern Ticino Province- Most eastern eastern Switzerland province-Zürich (Gotthard route, this needs the most developed railways).
3. The Simplon route (which is at the moment the gotthard VP) to Bern. This one is well implemented but the Traintracks are wrong. The Simplon route goes to Bern (as it does at the moment), but has no direct connection to Zürich. This is probably simulating the Gotthard route but as said it is too far west.
One can argue to add the St Berhhard crossing from the northeastern most Italian province into Wallis
2. While the Balance of Power between the Federal Government and the Cantonal Government does make sense (it is still going on), during World War II the Balance of Power between the French and German speaking part was way more important for the future of Switzerland.
Partially a reason why Guisan was elected General was because he was from the French part. The Assembly was worried that if they pick a German-Speaking General the French will feel even more underrepresented. This also behind the background that in 1932 the Swiss Army helped putting down protests (Anti German ones) in Geneva with force (13 people were shot) and the Army hand picked the soldiers from German speaking ones.
This would also makes sense with the background of Alt-History and choosing sides: Guisan itself had secret plans helping the French for example. The Western parts were very inclined to side with France, the German speaking ones with Germany. It would make sense to have this balance deciding wether to stay neutral or pick a side.
3. While I think the Milita system is a brilliant pick and the special representation in the recruitment law is nice, the Swiss army had special divisions and not only one (two with the mountaneers) template. So we can have locked templates but it would be nice to have more than one. There should be at least 4, maybe 5.
1. A simple infantry template (the most available) with line inf and support engineer, field hospital and recon
2. Th Artillery Divisions with line inf and support artillery, engineer and field hospital
3. AT Divisions, line inf, support AT and engineer
4. AA Divisions, line inf and support aa + Engineer
(5. A tank division)
This would somewhat represent the swiss army better.
4. I would like for Switzerland to have some sort of anti bombing spirit (especially for strat-bombing). Most alpine airports were built into mountains, so while the runway was exposed, the aircraft were safe. Same for many other important depots and storages. Switzerland was able to move goods through the mountains.
So logistic Bombing and Strat Bombing should be harder against switzerland.
5. Economically Switzerland traded the gold (or used the gold trade in general) to buy ressources like tungsten, steel and coal. It would be nice to get offmap civs for the trade that can be used to buy important goods from germany and italy (even if they are in closed economy).
So thats my 2 cents, hope you can have a look into it.
