I should make it clear,

我该说得详细一些
they start out walking at a certain clip.

他们疾驰前进
By the way, it's critical that they should stay in formation;

顺便说一下这是在保持队形的前提下
nobody should get ahead of anybody else.

不能有人单独冲在前面
How do you do that?

怎么实现呢
With rhythm and in subsequent armies later in history,

通过节奏而根据历史记载
they used drums to maintain that technique.

后来的军队通过鼓来实现这一点
The Greeks did it by the playing of a flute like

希腊人通过类似长笛
or oboe like instrument that played a military tune

或双簧管的乐器发出指令
that had you marching forward at the right pace.

使之能以正确的步调前进
That was very, very important.

这非常非常重要
So you're marching forward at that pace,

所以大家步调一致地突进
