The ultimate funny trainer jet, even fought in the Congo (and according to some sources from Swedish and Belgian pilots, even won a dogfight against a Swedish J-29A there, although both planes managed to return to base).
A hypothetical Swiss tree being its own line could look something like this (I made this on a whim, probably missing a decent chunk of vehicles):
Rank I
Praga LT-H
Panzerjäger R 35 (f) [Not Swiss but a German modification of a French tank, however it is German, and the sole surviving model stands in the Swiss Armour Museum)
Rank II
Nahkampfkanone 1 (10.5cm)
Nahkampfkanone 1 (7.5cm)
Rank III
Nahkampfkanone 2
Panzerjäger G.13 (semi-unique Hetzer)
Rank IV
Leichtpanzer 51 (AMX-13, so maybe, maybe not)
Saurer Tartaruga
Panzer 58 (might be better as the first rank V, not entirely sure)
Rank V
Multiple versions of Panzer 61
Panzer 55/57 (Centurion, so maybe, maybe not)
Panzerjäger Taifun
Mowag Tornado
Plenty of other Mowag prototypes across this rank and the next
Rank VI
Early Panzer 68 versions
Mowag Shark
Perhaps some Mowag Piranha versions
Fliegerabwehrpanzer 68 (Second Gepard, because why not)
Rank VII
Panzer 87 (Leo 2A4, so maybe, maybe not)
Some more Mowag Piranha versions
Rank VIII
No clue really. The Swiss haven’t modernized their Panzer 87’s too much iirc. So maybe an IFV, but otherwise this line might end at Rank VII.
