Another possible explanation of the significance of depth

方阵纵深的重要性的另一种可能解释
is remember, our poor victim here.

就是记得刚才这位可怜的牺牲者吗
If you multiply her,

如果再多一些
then you want to have as much depth to fill in behind

你就需要在后面增加足够的排数
to close that hole as you can,

尽可能地填补缺口
so that that would make your phalanx more sturdy,

这会使你的方阵固若金汤
because you could take more casualties without breaking,

即使伤亡惨重也不影响阵容的坚固
that seems reasonable to me.

这在我看来是合理的
But again,I can't imagine how these guys fought

但我还是不能想象
in these circumstances.

他们怎么在这种情况下作战
I really can't see it.

我确实搞不清楚
I mean, it's a pity we can't kill people in experiments deliberately anymore,

我的意思是很可惜我们不能在试验中故意杀人
