So it's the moment where modern war, you could argue, begins.

因此可以说一战是现代战争的发端。

These were the forces behind modern wars and also, Mr Overy argues, much earlier conflicts between pre-state groups.

这些是现代战争背后的驱动力，而且奥弗里认为，也是前国家集团之间冲突的背后驱动力。

But, in modern war, the habit of ready and instant obedience is of much greater consequence than a considerable superiority in the management of arms.

但是，在现代战争中，随时准备服从的习惯比在武器管理方面取得相当大的优势更为重要。

In modern war, the great expense of firearms gives an evident advantage to the nation which can best afford that expense; and, consequently, to an opulent and civilized, over a poor and barbarous nation.

在现代战争中，火器的巨额开支给最有能力负担这笔开支的国家带来了明显的优势；因此，一个富裕和文明的国家，对一个贫穷和野蛮的国家。
