The wartime emergency procurement regulations are actually due to capitalists fearing they would overplay their hand.
For instance, the Germans are advancing victoriously towards Paris. If the capitalists still greedily force the army to buy equipment at high prices while the army is unable to pay, the final result would be the whole country being occupied by the German Army, leaving nothing for the capitalists.
This is clearly not in the interests of the capitalists.
To avoid this situation, the capitalists finally had a "conscience awakening," believing that during wartime they should be more restrained. Otherwise, it benefits no one. Therefore, they handed over some authority to the military.
"In short!" Gallieni put away the cigarettes on the table, calmly placing them back in the cigarette case: "If the military has a need and the Senate cannot provide alternative products, they have no right to interfere with military purchases."
