The Glass Backbone: Why the Army’s Logistics Will Break in the Next War

脆弱的脊梁：为何美军后勤在下一场战争中将难以为继

The United States Army spent the last two decades optimizing sustainment for permissive environments defined by uncontested supply lines, contractor support, and static forward operating bases. As the National Defense Strategy shifts toward strategic competition and multidomain operations, however, this efficiency-driven model has become a liability. In large-scale combat operations, victory will depend less on which force fields the most advanced weapons and more on which can sustain combat power under persistent attack. A lethal maneuver force without a survivable logistical backbone is simply a stationary target waiting to culminate.

在过去的二十年里，美国陆军一直致力于优化在宽松环境下的后勤保障，其特点是畅通无阻的补给线、承包商支持以及固定的前沿作战基地。然而，随着《国防战略》转向战略竞争和多域作战，这种以效率为导向的模式已成为一种负担。在大规模作战行动中，胜利不再取决于哪支部队拥有最先进的武器，而在于哪支部队能在持续的攻击下维持战斗力。一支致命的机动部队如果没有可生存的后勤脊梁，不过是一个坐以待毙的固定靶子。

The Weight of History: Lessons in Logistical Overreach

历史的重压：后勤过度扩张的教训

History provides stark, recurring warnings against neglecting the sustainment tail in favor of the combat teeth. A prime example is found in Operation Barbarossa, the German invasion of the Soviet Union in 1941. German mechanized formations shattered Soviet defenses and advanced hundreds of miles within weeks. Yet they rapidly outran their logistics network. The German high command had planned for a short, decisive campaign. It failed to account for the immense distances, the lack of paved roads, and the mismatch in railway gauges that prevented German trains from utilizing Soviet rail lines without extensive modification.

历史反复发出严厉警告：忽视后勤保障（尾部）而片面追求作战能力（牙齿）是极其危险的。1941年德国入侵苏联的“巴巴罗萨行动”就是一个典型的例子。德军机械化部队在几周内击溃了苏军防线并推进了数百英里，但他们很快就超出了后勤网络的覆盖范围。德国最高统帅部原本计划进行一场速战速决的战役，却未能考虑到巨大的地理距离、铺装道路的匮乏，以及铁路轨距不匹配导致德军列车在未经大规模改造前无法使用苏联铁路网的问题。

Despite unprecedented initial battlefield successes, the campaign inevitably faltered. Fuel, ammunition, winter clothing, and replacement parts failed to keep pace with the advancing Panzer groups. The famous halt before Moscow in the winter of 1941 was not primarily a tactical defeat inflicted by the Red Army; it was a systemic failure in sustainment. The Wehrmacht’s operational brilliance was entirely nullified by its lack of strategic endurance. The lesson here is clear: Operational reach is strictly dictated by logistical and sustainment capacity.

尽管初期在战场上取得了前所未有的成功，但这场战役最终还是陷入了停滞。燃料、弹药、冬装和零部件无法跟上装甲集群的推进速度。1941年冬季莫斯科城下的那次著名停滞，主要并非红军造成的战术失败，而是后勤保障的系统性崩溃。德军的作战才华因缺乏战略持久力而化为乌有。这里的教训很明确：作战触角（Operational reach）严格受限于后勤和保障能力。

Modern armies, fixated on the speed and lethality of their own mechanized and aviation assets, risk repeating this exact error if they assume that supply will keep pace with the maneuver force. Furthermore, the Army must unlearn the logistical lessons from Operations Desert Storm and Iraqi Freedom. In 1991, the US military spent six months building massive “iron mountains” of supplies in Saudi Arabia, completely unhindered by Iraqi interdiction. In 2003, while supply lines were stretched, US forces still enjoyed absolute air supremacy and electromagnetic dominance. In a future peer conflict, the US Army will not be granted a six-month, uncontested build-up phase, nor will it operate under friendly skies.

现代军队如果沉迷于自身机械化和航空资产的速度与杀伤力，并假设补给能跟上机动部队，就有重蹈覆辙的风险。此外，陆军必须摒弃从“沙漠风暴”和“伊拉克自由”行动中得出的后勤经验。1991年，美军在沙特阿拉伯花费了六个月时间建立起庞大的“钢铁之山”，完全没有受到伊拉克军队的干扰。2003年，尽管补给线被拉长，但美军仍享有绝对的制空权和电磁优势。在未来的同等对手冲突中，美军既不会获得六个月不受干扰的集结期，也不会在友军控制的空域下作战。

The Crucible of Ukraine: The Transparent Battlefield

乌克兰的炼狱：透明的战场

If history provides the theory, the ongoing war in Ukraine offers a brutal contemporary lesson: Modern armies collapse when they run out of logistics, not when they run out of weapons. Pervasive sensing, precision fires, and inexpensive drone systems have effectively eliminated the traditional rear area. Sustainment nodes, convoys, and distribution routes are now persistently exposed to detection and attack, making survivability and dispersion prerequisites for operational endurance.

如果说历史提供了理论，那么正在进行的乌克兰战争则提供了一个残酷的当代教训：现代军队的崩溃不是因为武器耗尽，而是因为后勤耗尽。无处不在的感知能力、精确打击和廉价的无人机系统已经有效地消除了传统的后方区域。后勤节点、车队和补给路线现在时刻暴露在侦察和攻击之下，这使得生存能力和分散部署成为维持作战持久力的先决条件。

During the opening phase of the invasion, the forty-mile-long Russian convoy that stalled north of Kyiv in February 2022 demonstrated how fuel shortages, maintenance failures, and interdicted movement corridors can immobilize operational maneuver. Ukrainian forces bypassed armored spearheads to strike vulnerable fuel and support convoys, exposing the mechanized formations’ dependence on uninterrupted sustainment. Multiple Russian formations stalled not because they were tactically defeated, but because their logistical support collapsed.

在入侵初期，2022年2月滞留在基辅以北长达40英里的俄军车队证明了燃料短缺、维护故障和补给通道被切断是如何让作战机动陷入瘫痪的。乌克兰军队绕过装甲先头部队，打击脆弱的燃料和支援车队，暴露了机械化部队对不间断后勤保障的依赖。多支俄军部队陷入停滞，并非因为战术上被击败，而是因为他们的后勤支持崩溃了。

As the conflict evolved into a war of attrition, the vulnerability of centralized logistics became even more pronounced. Long-range precision fires, particularly HIMARS, enabled Ukraine to systematically target Russian ammunition depots and rail hubs deep behind the front. Russia’s subsequent displacement of logistical nodes farther from the battlefield degraded both the speed and volume of artillery resupply, demonstrating how attacks on sustainment architecture can directly reduce combat effectiveness at the point of contact.

随着冲突演变为消耗战，集中式后勤的脆弱性变得更加明显。远程精确打击武器，特别是“海马斯”（HIMARS），使乌克兰能够系统地打击前线后方深处的俄军弹药库和铁路枢纽。随后，俄罗斯被迫将后勤节点向远离战场的地方转移，这降低了炮火补给的速度和数量，证明了对后勤架构的攻击可以直接削弱接触点的战斗力。

Core Vulnerabilities: Moving Bulk Class III and Class V at Scale

核心脆弱性：大规模运输第三类（燃料）和第五类（弹药）物资

To understand the scope of the problem, one must examine the staggering consumption rates inherent to large-scale combat operations. The two most critical vulnerabilities in the current US Army sustainment architecture are the diminished capacity to move bulk Class III (fuel) and Class V (ammunition) at scale, and the overreliance on centralized, easily targetable infrastructure. This is particularly apparent in the organic sustainment architecture of an armored brigade combat team, which consumes tens of thousands of gallons of fuel daily during high-intensity combat.

要理解问题的严重性，必须审视大规模作战行动中惊人的消耗率。当前美军后勤架构中两个最关键的脆弱点是：大规模运输第三类（燃料）和第五类（弹药）物资的能力下降，以及对集中式、易受攻击的基础设施的过度依赖。这一点在装甲旅战斗队的有机后勤架构中尤为明显，该部队在高强度作战中每天消耗数万加仑燃料。

Moving this volume of fuel from the division support area through the brigade support area and forward to the combat trains command post requires a massive fleet of heavy tactical vehicles. Current fuel distribution platforms remain large, lightly protected, and readily detectable by their thermal and electromagnetic signatures, while maintenance shortfalls and inconsistent operational readiness reduce available distribution capacity. The current distribution system lacks the physical resilience and protection needed to withstand the relentless deep-strike attacks expected from a peer adversary.

将如此大量的燃料从师支援区经由旅支援区运送到前线作战列车指挥所，需要庞大的重型战术车辆车队。目前的燃料分配平台体积庞大、防护薄弱，且极易被热信号和电磁信号探测到，而维护不足和作战准备状态不一致进一步降低了可用的分配能力。当前的分配系统缺乏抵御同等对手预期中持续远程打击所需的物理韧性和防护能力。
