Gen. Robert H. Barrow, USMC, once said that “Amateurs talk about tactics, but professionals study logistics.” That’s true in many enterprises, but in warfare, the side that neglects logistics is likely to be the loser. Keeping soldiers fed, clothed, and armed is the very essence of effectively prosecuting a war, and the long logistical chain from rear supply depots to forward action is what makes that possible.
Armies have had millennia to optimize logistics, and they have always maximized use of new technologies to position supplies where they’re needed. Strong backs of men and beasts sufficed for centuries, supplemented by trains in the 19th century and supplanted by motor vehicles in the 20th. Later, aircraft made an incalculable impact on supply chains, allowing rapid mobilization of supplies and supporting the industrial scale death and destruction of the 20th-century’s wars.
