>But do 2S get promoted to 3S without getting into a 3S position?
I think it's possible in theory (I'm not 100% sure, I would have look the regulation for it and I can't be bothered), but in practice no.
I think in theory you can be promoted to any rank any way.
I'm not sure if I'm explaining this properly but 4S and above are ranks that are not ranks, but titles.

>3S is the "designated desk jockey position", and 4S and 5S in theory should work like a 2S, just with a bigger unit under their command?
No, it's just that 3S and above you just have too many troops under you to micromanage them. They might do it for morale or inspect specific points they are worried about but the french army has been brigadized, so the highest "leader of men" is the commander of a brigade, so it's his job. A 3S job is to worry about how the brigades are moving (both his and the enemy).
In this day and age a 3S in a combat operation will have an interarm command, with one or two army brigades, an air component, possibly a navy component.
It's a completely different job than "just more people".

>Are they actually understaffed, or just about the right size?
It's a bit bloated, but not too bad compared to the NATO average. There are lots of military schools (which for historic reasons can't be headed by a colonel or God forbid, a civilian), lots of DGA positions, lot's of phantom command position (we had avoided that for years but now that we're back in NATO command + the fucking new EU command it's a fuckfest), lots of defense advisers (for actual diplomatic missions) which end up making a lot of stars compared to the actual units in the french army.
But it's a minor issue because it's hard to tell how many of those would be not-retired (since they don't retire unless really invalid) and payed essentially the same (except for not doing anything, so…)
>Honestly, it's surprising how the French military seems to be so sensible despite centuries of traditions. Is 2S the lowest rank because of those traditions, or is it because of NATO requirements?
Brigadier is a french term, it's the rank above colonel.
Brigadier were one star on colonel insignias, you had basically three ranks of colonel, lieutenant-colonel, colonel, brigadier. A brigadier would be an experienced colonel in command of more than one regiment but not a proper brigade and not a general, he could be for example the leader of men when the general de brigade (2S) would concentrate on logistics and planning or he could lead a half-brigade (which is a thing). It was fairly rare (colonial thing/ad-hoc commands, mostly) to begin with and it was confusing because two ranks of brigadiers existed (one being what they call corporals in the cavalry) so it was axed after WWII, probably to have same numbers of generals ranks as the UK/US.
Géneralissime is 6 stars. Maréchal is 7.

>so sensible
It's not. General and Colonels should not lead from the front unless absolutely necessary. It sounds cool on paper but the amount of time French superior officers got killed because they were in the middle of battle instead of supervising the battle is stupid. And without superior officer the battle tend to be lost.
Second it creates "a chief culture" in which basically every word of a general is law… even if he's being fucking retarded and his entire staff knows it, ratting him out to his superior is the worst offense any officer could do. Countless battle have been lost because of that.
It's a more "honorable" way to manage an army, but ultimately it's a coin toss.
