On the artillery side the French were committed to 'guns' vs howitzers. In reverse of US and German weapons doctrine the higher velocity/range gun was the standard & the howitzer a specialty weapon. The bulk of the mew models were characterized by significantly longer range than comparable caliber howitzer models. While there were some trade offs in terrain problems, ROF, tube life, weight, ect the French sought a tactical advantage from the combination of greater range and their techniques for massing artillery fires. By 1940 this existed in terms of the technique, and the weapons were in production and distribution.
While the aging 75mm gun could not be replaced in bulk in 1941-42 About everything else in the corps & army artillery groupement would be a modern long ranged cannon, consistently out ranging the comparable German 10.5cm & 15 cm howitzers. If any of the production goals of the French I've seen are accurate then at the end of 1941 the German corps & army echelon artillery is going to be overmatched both in numbers and technical capability.
On a seperate level the French had complete design and prototypes of purpose built armored artillery. Limited production of test equipment had begain in early 1940. These were not armored 'assault guns' like the StuG, but fully armored self propelled indirect fire weapons More akin to the post WWII tracked & enclosed artillery weapons. Despite the identification of the need for a protected tracked SP cannon the German provision was slow, with only some cobbled models built in 1940 & nothing purpose built yet tested. To compound French foresight in this they were also testing armored & tracked command and observation post vehicles. Intended to act as mobile CP for the cannon Groups these vehicles carried range finding, direction finding, & general survey equipment; along with radio and telephonic communications.
My research on this is nowhere complete, but suggests a really deadly artillery arm as 1940 spins off into 1941.
