The French are notorious for spending shit tons of money on useless outdated garbage. Most notable is their tank force. During the period from 1933-1939 France was renowned for having the "best" armoured force in the world, its tanks were on paper simply the best, the Infantry tank Char B1 was the best and most numerous heavy tank in Europe, its size also meant that it carried a two-way radio. Supplementing this was the Sa35, regarded as the best tank in the entire world, mostly due to its very good 47mm gun combined with its good armour and mobility, it was the best all-around tank, and the pinnacle of pre-war medium tank design that mid-war medium tanks would try and embody and would be furthered by MBTs. The problem with the French tanks is that although they were the best on paper, the French lacked any real practical experience in designing them. As a result French tanks were complete rubbish in an actual battle. Their guns, although very good, were slow to reload due to ALL french tanks having one man turrets, this meant that the commander was also the radio operator, the loader, and the gunner and could do none of those very well. As well French tanks had terrible off-road suspension, small ground clearance, and awkward hull shapes that tended to get them stuck in ditches or tip over on sharp inclines. As well they lacked radios beyond the B1, meaning that French tanks had to often communicate using signal flags or morse lamp. The Germans by 1939 were almost the complete opposite, their tanks were on paper dreadful, they were heavier, slower, and more lightly armed than the Allies's counterparts, with the best in service gun being the 3.7cm on the Panzer IIIs and Panzer 35(t)s/38(t)s with the 5cm universal gun being too expensive too see production at the time. However the Germans had built their tanks in cooperation with the Soviets and as such had extensive field experience with tanks, leading both the Soviets and Germans to prioritize ergonomics, off-road maneuverability, communication, and ruggedness. This meant that German tanks had 5 crewmen per tank compared to the French's 2-3. As well the brand new suspension created by Porsche allowed German tanks to travel over rough ground over large distances without needing replacement, something that French tanks found impossible due to their fragile suspension and low ground clearance. In 1940 France had 1240 "modern" tanks at its disposal with around 2000 slightly outdated tanks that could still pierce the armour of any German tank, while the German could muster only 570 modern tanks after Poland and 600 Czech models, bringing their practical strength to around 1100 tanks, the Panzer IIs and Is being redundant. However in reality the Germans had more tanks, entirely due to how divisional organization worked in both armies. In France tanks were not their own separate force, but integrated into the various arms of the army. Infantry and Cavalry tanks were not just monikers but quite literal descriptors, they were part of the Infantry and Calvary corps respectively. And they were in every single French division in the entire French army, working the same as any artillery or support division. In effect the French could muster anywhere from 20-80 tanks per division, with an experimental "Heavy" tank division mustering 200 tanks with 100 Char B1s, but only 2 of these every existed. What this meant was that the French, despite having more tanks than the Germans, were always outnumbered tanks wise. The Germans had concentrated their tanks into independent Panzer Corps, with supporting infantry and integrated aerial support to make up for heavy artillery, they were basically their own micro-army that could meet and overtake any opposing equivalent force with focus being on staying mobile. This meant that the Germans had 200 tanks per division against France's max 80 tanks per division, the French would have had to field at least 3 division for every German division, while more often they would have had to field, and coordinate 5 division to properly outmatch a single German division, and given the French's terrible communication system meant that was nearly impossible.
