"General." Bo Yata pondered for a moment: "If we cooperate, the bullets and shells for the French Army can be produced by FN, which can save a lot on transport costs and time."
Shire responded with an "Hmm": "Indeed, that would bring advantages, but I believe this is also Belgium's problem."
The French Army is here to liberate Belgium; those who should be more concerned about this issue should be Belgium, not France. Producing ammunition for the French Army is a given and cannot be used as a negotiating condition.
Bo Yata felt slightly embarrassed; he had only thought about the reasons and hadn't considered this point.
