Provisions should be arranged before an army is mobilized.

解释 ( paraphrase )
这是古人在作战中总结出的经验。粮草是打赢战争的关键的关键。士兵上前线，必须保证充足的粮草、畅通的粮道。这条谚语告诉我们：无论是打仗或坐任何一件事，都必须事先做好充分物质准备，才能有成功的把握。

This proverb stresses that whatever we do, proper preparations should be made in advance to ensure success.

兵马：兵士和战马，泛指作战部队。
         Soldiers and horses; generally, an army.

粮草：军用的粮食和草料。
         Food and fodder provided for an army. 

造句 ( example )
兵马未动，粮草先行！千万人民除了保证前线军需弹药粮草的供应处，还不顾一切艰苦，热情地转运与看护伤员。
